UM024002-0512 Introduction
Z8051 On-Chip Debugger and In-System Programmer
The Z8051 On-Chip Debugger
The Z8051 On-Chip Debugger enables a development PC to communicate with your target
Z8051-based MCU. The OCD interface is used to connect the development PC and the Z8051
MCU. The OCD controls the Z8051 MCU’s internal debugging logic, including emulation, step
run, monitoring, etc., and can read or change the value of the Z8051 MCU’s internal memory
and I/O peripherals.
The Z8051 OCD supports emulation and debugging at the maximum frequency of the MCU
and can support In-System Programming (ISP), thereby eliminating the requirement for an
expensive emulator system.
The Z8051 OCD Debugger works with the Microsoft Windows XP, Vista (32/64) and
Windows 7 (32/64) operating systems.

hex file and load these files to memory.
7. After the map/symbol files are loaded into memory, the debugger resets the target
MCU and moves the MCU’s program counter to
0000h.
8. Save the current debugging environment to the hard drive of your development PC
and exit the Debugger by selecting
Exit from the File menu.
Emulation Menu
The Emulation menu, shown in Figure 13, lists the controls for starting or stopping an
emulation routine. Use the Emulation menu to control the flow of code execution for
debugging purposes.
15
Figure 13. The OCD’s Emulation Menu
The remainder of this section describes the features of the Emulation menu.
Reset & Go
This menu selection starts an emulation from the 0000h address upon a reset of the target
MCU, and functions in a manner similar to a Power-On Reset. Emulation continues until a
breakpoint occurs or the user stops the emulation process. The Reset & Go menu is disabled (greyed out) in the Emulation menu during emulation.

User Manual
Go From
The Go From menu selection starts emulation from a user-specified address, and is used to
debug each software module. The user is prompted to enter an emulation start address, as
follows:
•
Using LINEAR ADDRESS Mode, enter a 20-bit address directly.
•
Using BANKED ADDRESS Mode, enter 4 bits of bank and 16 bits of address. Each
bank size is smaller than or equal to 64 KB.
The Go From function is disabled (greyed out) in the Emulation menu during emulation.
Go
The Go function begins emulation from the current address, which can be characterized
as:
16
•
The last known (stopped) address that was held in the Program Counter from a previ-
ous emulation session
•
The point at which a break occurs, such that:
– If a break occurs before the breakpoint, the current address is the PC breakpoint
address
– If a break occurs after the breakpoint, the current address is the next execution
address of the PC breakpoint address
•
If the target MCU was reset, the reset address is 0000h.
The Go function is disabled (greyed out) in the Emulation menu during emulation.
Step
The Step function is used to debug each instruction flow and process one step at a time;
the target MCU program flow will execute only one instruction at a time, then halt.
If the MCU receives a CALL instruction, it executes a Step run into the subroutine. If
MCU is in STOP Mode, the Step run is ignored. The Step function is disabled (greyed out)
in the Emulation menu during emulation.
Step Over
The Step Over function is used to check main program flow when each subroutine had
been tested already. This function is similar to the Step function, with the exception of its
subroutine call. If the MCU receives a CALL instruction, the debugger assumes the CALL
and its subroutine to be one instruction, even if the subroutines are nested.
UM024002-0512 The Z8051 On-Chip Debugger
Z8051 On-Chip Debugger and In-System Programmer
User Manual
If the Step Over function reaches a PC breakpoint condition, emulation is halted. This
function is disabled (greyed out) in the Emulation menu during emulation.
Step Auto
Using the Step Auto function, a step run is executed every 100 ms; execution will continue
unless the user halts it. This function is disabled (greyed out) in the Emulation menu during emulation.
Break
Using the Break function, emulation is halted immediately, even if the MCU is in STOP
Mode. This function is disabled (greyed out) in the Emulation menu during emulation.
Reset
The Reset function releases a hardware reset signal to the target MCU, which is then reinitialized. Emulation is not halted when the MCU is emulating; however, this function has
no effect when the target MCU is idle. The Reset function is enabled in the Emulation
menu whether an emulation is running or is idle.
17
Break/Configure Menu
The Break/Configure menu, shown in Figure 14, lists PC breakpoint control, device configuration and hardware test functions.
Figure 14. The OCD’s Break/Configure Menu
Clear ALL Break
The Clear ALL Break function immediately clears all PC breakpoints. This menu is disabled (greyed out) in the Break/Configure menu during emulation.

Peripheral Control
Selecting the Peripheral Control function from the Break/Configure menu prompts the
user to determine whether the target MCU’s internal peripheral functions should continue
to operate or remain idle, as shown in Figure 18. These peripherals are always running
during emulation by default.
Figure 18. Peripheral Control Dialog
The purpose of the Peripheral Control function is to tell the OCD whether the peripherals
UM024002-0512 The Z8051 On-Chip Debugger
should be stopped or continuously run during Break (Debug) Mode. All peripherals,
Z8051 On-Chip Debugger and In-System Programmer

including the PLL and ADC functions, will be stopped when selecting Stopped concur-
rently
. The Peripheral Control menu selection is disabled (greyed out) in the Break/Con-
figure menu during emulation.
The Peripheral Control function does not control each peripheral individually.
Chip Configuration
The Chip Configuration function is used to configure the target MCU’s I/O pin function,
oscillation method, code protection, etc. Each device series features different configurations. If a configuration changes, the user must turn off power to the target MCU, then
power it on again. As a result, configurations can be influenced when power rises to operational voltage.

The Configuration dialog box shown in Figure 19 offers an example con figu ration for the
Z51F0811 device.
