However, the M34282T5-OPT cannot be connected to the foot pattern of the MCU package (20P2NA or 20P2E/F-A).

For this connection, you need three accessory parts listed below:

(1) 40-wire half-pitch cable (40 cm) (2) Pitch converter board PCA4029 (3) 20-wire normal-pitch cable (10 cm)

Table 4.9 lists the connector signal assignments of the 20-wire normal-pitch cable. Figure 4.8 shows the pin layout of the 20-wire normal-pitch cable.

5. Precautions to Be Taken When Debugging

5.1 Reset

The M34282T5-OPT can be reset by the reset command of emulator debugger RTT72, but cannot emulate device operation at power-on reset. Use an evaluation MCU (OTP version) to verify the operation associated with power-on reset.

5.2 Capacity of Internal Memory (ROM, RAM)

The M34282T5-OPT is equipped with the M34282E2GP as an evaluation MCU. The RAM and ROM areas that can be referenced by emulator debugger RTT72 are specified by switches SW2 and SW3 as listed in Table 5.1.

5.3 Watchdog Timer

With the M34282T5-OPT, the watchdog timer cannot be operated. Therefore use an evaluation MCU (OTP version) to verify the operation associated with the watchdog timer function.

And with the M34282T5-OPT, when executing WRST instruction, the check pin TP4 outputs "H" level (see Figure 5.1), so you can check the initializing cycle of the watchdog timer by monitoring the pulse width frequency of TP4.

5.4 System Clock

Depending on how the instruction clock is set, use the M34282T5-OPT in the range of frequencies listed in table 5.2.

When the instruction clock is set to STCK = f(XIN) and the system clock frequency is over 500 kHz, the emulator may not work properly.

Table 5.2 Operating frequencies of the M34282T5-OPT

Voltage

3 V

Instruction clock

STCK = f(XIN)/8

STCK = f(XIN)

* To change the system clock frequency, change the clock frequency of the oscillator circuit board

OSC-2. For details about the oscillation circuit constant, consult your oscillator manufacturer.

5.5 Real-time Capability of Timer

As the evaluation MCU is active even when program execution is stopped or when a command is executed, its timer values are modified.

Examples: (1) When single-stepping instructions

(2) After program execution stopped

5.6 Power-down Mode

Although the M34282T5-OPT can execute a program using the POF instruction, there are precautions and restrictions listed in Table 5.3.

Table 5.3 Precautions for power-down mode.

Frequency

4.0 MHz or less 500 kHz or less

Description

Although SAFE and ERROR LEDs of the PC4000E light up in the power-down mode, it is not

an error condition. Do not use the POF instruction when single-stepping a program. The POF instruction can not

be executed correctly when stepped through. No debug command of emulator debugger RTT72 can be executed. In the power-down mode,

execute the debug command after resuming by the key-on wakeup function. The real-time trace result of the area including the POF instruction cannot be displayed

normally.

( 24 / 38 )

5.7 Program Execution (G, GB)

The PC4400 and the M34282T5-OPT's hardware are subject to the following restrictions with respect to the operation of the program execution commands (G and GB).

(1) Continuous description of instructions

Hardware break points set in a continuous description of instructions following one after another do not cause a break to occur in the continuous description of instructions. A break occurs only after fetching the address where the continuous description of instructions is discontinued. (See Program example 5.1)

However, a break does occur even in a continuous description of instructions when an external trigger break or forced break is encountered. For execution to be resumed in this case, you need to make sure that the execution start address is next to the continuous description of instructions. (See Program example 5.2)

Program example 5.1

POINT: LA 1 ; Continuous description of instructions POINT+2: XAM 3

If a break is set at POINT, execution is halted immediately before the XAM instruction at address POINT+2.

LA 0 LA 2

Program example 5.2

LA 0 POINT: LA 1 ; Continuous description of instructions POINT+1: LA 2 POINT+2: XAM 3

If a forced or external trigger break is applied at POINT, execution is halted at POINT+1. When resuming program execution after the break, make sure that the start address is at POINT+2, an address immediately after the continuous description of instructions is discontinued.

( 25 / 38 )

(2) Skip instructions (e.g. SNZP, INY, DEY, SZB, SEAM, SZC and RTS)

In cases when a skip instruction skips the next instruction, a break point set in the skipped instruction does not cause execution to halt. (See Program examples 5.3 and 5.4)

Program example 5.3

LXY 0,0

SZD POINT: B jmp_adr ; Skip when D(0) = 0 POINT_A: TAM 0

•

If a break point is set at POINT, D(0) = 0: Execution is halted immediately before the instruction at POINT. D(0) = 1: Execution is NOT halted because the instruction at POINT is skipped. To halt execution immediately after a skip instruction, set break points at POINT and POINT_A.

Program example 5.4

INY POINT: TABP ; Skip when (Y) = 0

LA 0

•

If a break with pass count is set at address POINT, the count is taken and execution is halted only when the instruction at address POINT is executed.

( 26 / 38 )

5.8 Pulldown Transistor Control

Since ports D4 to D7, E0 and G0 to G3 contain emulation circuits, you can not control the pulldown resistors using the pulldown control register. If you want to use the internal pulldown resistors, turn on switches SW4 to SW10 when occasion demands. With the M34282T5-OPT, the port's resistance value of the pulldown resistor is 150 kΩ.

When changing the resistance value of the pulldown resistor, replace RA1 (ports E0, G3 to G0) and RA2 (ports G7 to G4) on the M34282T5-OPT. For the position of the pulldown resistor, see Figure 4.3.

5.9 Port I/O Timing

(1) Port input timing

Port input timings are the same as with the actual MCUs.

(2) Port output timing

When using the M34282T5-OPT, output timings are different from those of the actual MCUs for the ports D0 to D7, E0 and G0 to G3 that are configured with port emulation circuits.

With the actual MCUs, changes occur at the beginning of the T4 state of an output instruction. With the M34282T5-OPT, changes occur at the beginning of the T2 state of the next output instruction. Figure 5.2 shows the port timings of the actual MCUs and M34282T5-OPT.

Port output timings of ports E1, E2 and CARR are the same as with the actual MCUs.

5.10 Port I/O Characteristics

With the M34282T5-OPT, port I/O characteristics are different from actual MCUs because there is an emulation circuit in ports E0, G0 to G3 and D0 to D7. Table 5.4 lists port I/O characteristics of the M34282T5-OPT.

6. LED of PC4000E

6.1 LED Indication at Emulator Startup

The emulator checks the PC4400 system immediately after startup. During system check the PC4000E's SAFE LED flashes and the ERROR LED stays on steady. If the SAFE LED does not flash, it means that the system check program is not operating. In such a case, check whether the PC4000E, PC4400 card cage and each circuit board are fitted correctly. When the system check is completed, the emulator status is indicated by the LEDs on the PC4000E.
