target board. Plug the other end of the cable into the matching black emulation cable connector in front of the emulator (see Figure 2-2).

NOTE: The inductance and capacitance of the emulation cable may affect the signals to and from the

emulator and target board, especially if the target board has low-current drivers, pull-ups, and pulldowns.

Setting Up the Z8ICE000ZEM Oscillator and Option Jumpers

The oscillator and option jumpers are accessible on the emulator. Refer to Figure 2-2 for emulator jumper locations. Refer to Table 2-1 and Table 2-2 when setting up the jumpers. Also refer to Appendix C for the complete Z8ICE000ZEM Emulator Schematic Diagram.

The option jumpers allow you to configure things like whether the emulator provides power to your design on the VCC pin of the emulated Z8

PLUS

device, and how the clock pin is connected.

The clock for the emulated device can be provided from an oscillator in the emulator or from a TTL-level clock on your design. For electrical reasons, the clock cannot be supplied from the oscillator on your design until you are done using the ICEBOX and have either programmed an EPROM or OTP Z8

PLUS

and installed

it in your design.

WARNING!

If your design already has a power supply, do not power your design from the emulator VCC pin on location JP1 of the Z8M001 board.

Power Up

If anything unusual (such as unexpected sounds and smells) occurs the first time you turn on the power supply, quickly turn off the power supply and check your connections. If your power supply allows voltage adjustment, ensure that adjustment is within specified range (see “Hardware Specifications” section). If your power supply has a current meter, ensure that the emulator is drawing within the rated current.

After emulator power-up, press the MASTER RESET button to reset the emulator. (Pressing the TARGET RESET button resets only the Z8M001 ICE chip.) If the emulator is not powering your design through the VCC pin, turn on the power supply of the design.

Power Down

When powering down, follow the procedure described below:

1. Press the TARGET RESET button on the emulator.

2. Power down the target application board (if using its own power supply).

3. Remove the target pod.

4. Power down the emulator.

program. Execution stops when it hits a breakpoint, a STOP or HALT instruction, or when you click on the HALT button. After a GO, the user should not attempt any further operation except activating the HALT button to terminate execution.

HALT Activation of this button terminates execution. If a GO command has been

issued, the HALT button must be activated for the RESET command to take effect.

JUMP Activation of this button sets the program counter to the address in the Jump

ﬁeld (ﬁeld 6). The corresponding line of code is highlighted in the Trace Buffer (ﬁeld 8) and Code List (ﬁeld 9) ﬁelds.

RESET Activation of this b utton causes a jump to the address located at the reset vector

location in the code. If a GO command has been issued, the HALT button must be activated for the RESET command to take effect.

SET BRK Activation of this button sets a breakpoint at the address in the Set

Breakpoint Input ﬁeld (ﬁeld 2). The address is then added to the Breakpoint List (ﬁeld 1).

RESET+GO Activation of this b utton resets the microcontroller and sets the program counter

to the beginning of the program. Execution stops at the ﬁrst breakpoint setting or at activation of the HALT button.

STEP Activation of this button advances the program counter the number of steps in

the Step Editing ﬁeld (ﬁeld 7). When the value is set to 1, the STEP button single-steps through the code without causing a RESET. NOTE: Nev er process a STEP command through the HALT or STOP instruction in your code; communication closes at the HALT or STOP.

STEP OVER Activation of this button advances the program counter a single step. That is,

one assembly instruction is executed. When the current instruction is a CALL instruction, subsequent code is executed in real time until the program returns from the subroutine.

Programming Options

Several OTP operations can be performed:

Table 3-1. OTP Operations Functions

Operations Functions Performed

BLANK CHECK Checks whether the OTP device is blank. VERIFY Compares the contents of the Code Memory and the OTP device. EXAMINE Load the content of the OTP device to code memory PROGRAM Writes the contents of the Code Memory to the OTP device. OTP CHECKSUM Calculates the Checksum of the OTP device only and displays it on the screen. RAM CHECKSUM Calculates the Checksum of the RAM and displays it on the screen. EPROM Protect Disables the EPROM mode to prev ent code retrieval. Also inhibits Factory Test

mode.

RC Oscillator Sets the device to operate with an RC clock source. QUIT Quit OTP operation.

NOTES:

1. To obtain a Data I/O (such as UniSite, 3900, or 2900) calculated Checksum, the user should first download the file with 00 padding option, then perform the OTP programming. Data I/O fills its memory with 00 after power up.

2. Checksum differences may occur. During user-program download, the memory is padded with code outside the user program memory if the user program is less than the emulation memory. The memory is padded with either 00, FF, or nothing according to user selection. This does not effect the user program; however, it does effect the calculation of the Checksum during the OTP programming because the Checksum is calculated through out the whole memory size of the OTP.

Command Status

This ﬁeld contains a message display area and a progress bar that is activated when one of the OTP operations are performed.

Device Serialization

A user-specified serial number can be programmed into the OTP device. The serial number can be changed at any time before it is programmed into a device. The characteristics of the serial number are specified in the Device Serialization section of the OTP window.

Method

Three methods of creating a serial number are available: sequential, pseudorandom, or none.

UM000500-Z8X1098 3–25

Z8ICE000ZEM User’s Manual Summary of Menus, Commands, and Operations ZiLOG

¥ Sequential Mode - The serial number increments by one after each device is programmed. ¥ Pseudorandom Mode - The serial number is generated according to the following algorithm:

r[i+1] = (a * r[i] + b) mod 2^N

where r[i+1] is the new serial number

r[i] is the last serial number

a = 1909

b = 221 571

N = number of bits in the serial

number

Example: Entering 1000 in the Address box, selecting 4-Bytes as the Serial Number Size, and entering 12345678 in the Serial Number box outputs to the screen as follows:

%1000 = %12

%1001 = %34

%1002 = %56

%1003 = %78

¥ None

Serial Number Size

The Serial Number Size field specifies length in number of bytes the serial number occupies in memory. This field is not available when Device Serialization is set to None.

Serial Number

Enter the exact serial number in the input field. Specify the format of the number as either hexadecimal or decimal. If a decimal number is input, the number is converted to hexadecimal for storage in memory. This field is not available when Device Serialization is set to None.

Address

EMULATOR OPERATION

Hardware Reset

When you press the emulator RESET button (or power-down, then power-up), the initial screen and the ZiLOG logo are shown while the ICEBOX goes through the initialization sequence.

Pressing the RESET button resets most of the settings that you establish using the GUI. For example, the emulated ROM size is reset to 4 KB, and all 32-KB breakpoint RAM is cleared.

NOTE: After RESET, you must wait a minimum of 5 seconds (for completion of selftests) before starting

the GUI software.

If you press the Hardware Reset while the GUI is running, a communication error dialog box appears with the following message: Out of synchronization with the emulator. This message appears when the power or RS-232C cable is removed, or whenever the ICEBOX emulator and the host PC have failed to properly communicate with each other. You have three responses to this message: Abort, Retry, or Ignore.

Abort Quits the GUI. Retry Resets the GUI by reinitializing. You are returned to the initial purple screen with the ZiLOG

logo.

Ignore Attempts to reestablish communication between the GUI and ICEBOX emulator without

reinitializing.

ROM Size

The ICEBOX has the selectable ROM size of .5K to 8K.

Breakpoint Implementation

The emulator bases its breakpoint facility completely on addresses, rather than on inserting special TRAP instructions into the program, which enable the setting of breakpoints in Program Memory on your target board. The ICEBOX uses a 32Kx1 static RAM for each cycle emitted by the Z8 ICE chip during code execution to implement the breakpoint function in hardware.

RUNNING MULTIPLE EMULATORS

The Z8 ICE GUI allows several emulators to run at the same time, if your PC has more than one communication port.

NOTE: Running multiple emulations (two or more emulators running simultaneously) requires more

memory than single-emulation operation; therefore, we recommend using a PC with 8-MB RAM or 16-MB RAM for Windows 95. In addition, two or more communication ports are needed when running multiple instances. Ensure that there are no COM port interrupt conflicts if installing additional COM ports via an add-on board.

TROUBLESHOOTING GUIDE

INTRODUCTION

Before contacting your ZiLOG representative or submitting a Problem Report, please follow these simple steps. Also, check the Precautions and Limitations sections in the Data Sheet included with your emulator to eliminate other possible known problems. If a hardware failure is suspected, contact your local ZiLOG representative for assistance.

INITIAL SCREEN DOES NOT APPEAR

The initial ZiLOG screen does not appear after selecting a COM port, and a message is displayed that begins “Time-out while reading...”

1. Check the RS-232 cable connection or try another cable that is known to be good.

2. Check if transmit/receive signals need to be swapped. NOTE: On some DB9 connectors for the COM ports, the transmit/receive signal may be swapped and a

Null Modem adapter may be required.

3. Verify that the power supply is connected and turned ON, and that power is available.

4. Verify that the power supply is set at the correct voltage.

5. Check that the power supply can supply the required 0.5 Amp current to the emulator.

6. Check selected port using another application or select another COM port.

7. After resetting the emulator, wait 5 seconds (minimum) before running the GUI software.

VCC CONTENTION

To avoid VCC contention when a separate VCC is supplied to the target, ensure that jumper JP1 is not connected.

SELF TEST FAILURE

1. If any of the self tests fail, ensure that the target crystal labeled Y1 and Y2 is securely in its socket; then check U18 for damaged, broken, or bent leads or cold solder joints.

2. If “Monitor RAM fail” appears, then check U13 for damage or broken/bent leads/cold solder joints.

3. If “Break point RAM fail” or “User RAM fail” appears, then check U12 or U13 for damaged, broken, or bent leads or cold solder joints.

4. If the failure recurs after pressing the MASTER RESET button, power-down the emulator, then power it up again, and press the MASTER RESET button again.

5. The OTP chip should be removed from the socket during power up.

OTP PROGRAM FAILURE

1. Reset OTP device in socket and make sure there is good contact between socket and device leads, then reprogram the OTP device.

2. Check for a worn socket. Replace the socket if required.

3. Additional troubleshooting tips are provided in the OTPPROG.TXT file or icon.

HALT BUTTON DOES NOT STOP EMULATOR EXECUTION

If the application inadvertently goes into Stop mode, the only way to halt the emulator execution is by doing a Stop-Mode Recovery (as defined by the user program). You may also reset the application using the TARGET RESET button.

CHECKSUM DIFFERENCES

Checksum differences may occur when during download the following three conditions occur:

¥ User program is smaller than emulation memory. ¥ User-program memory outside the user program is padded with code. ¥ The Nothing item is selected in the Memory Pad With section of the Download to Z8 Code Memory

dialog box.

When this situation occurs, results of the user program are not affected. However, the calculation of the Checksum during OTP programming is affected because the Checksum is calculated throughout the entire OTP memory area.

SLOW RISE AND FALL TIMES

Low-current pull-ups/pull-downs/drivers may exhibit slower rise and fall times when the emulation cable is used due to additional inductance and capacitance of the cable.

ÒCANÕT OPEN WINDOWSÓ MESSAGE

If the “Can't Open Windows” message appears while attempting to open a window using the GUI software, there may not be enough memory within the Microsoft Windows environment to properly run the GUI software. Try closing the other active applications or exit and reenter the Microsoft Windows environment.

ÒOUT OF SYNCHRONIZATION WITH THE EMULATORÓ MESSAGE

This message appears whenever communication between the emulator and the PC is interrupted.
