Figure 3.10 Replacing the MCU

CAUTION

Cautions for Replacing the MCU:

• Before replacing the MCU, be sure to shut off the power supply.

• When mounting the evaluation MCU, be sure to match the No. 1 pin. Incorrect insertion may cause a fatal damage to the MCU.

• When opening and closing the IC socket, hold the adapter horizontally. Otherwise the inside of the IC socket may become damaged and cause an electrical insulation failure.

• When debugging a 4583 or 4584 Group MCU, it is necessary to replace the MCU to the included M34584MD-001FP and change the setting of switch SW4. For switch setting, see "3.3 Switches" (page 13).

Chapter 4. Precautions to Be Taken for Debugging a Program

4.1 Reset

The M34519T-MCU uses a 74HC14 for its RESET signal input buffer, so that its electrical characteristics differ from those of an actual MCU. Table 4.1 lists the RESET signal input characteristics of the M34519T-MCU.

Table 4.1 RESET signal input characteristics

H-level threshold voltage

L-level threshold voltage

Hysteresis voltage

4.2 Watchdog Timer

The M34519T-MCU does not have an operational watchdog timer. Therefore, use an evaluation MCU (OTP version) to verify the operation associated with a watchdog timer.

The M34519T-MCU outputs a signal whose waveform is shown below from check pin TP5 during WRST instruction execution cycles. This signal allows you to check the initialization cycle of a watchdog timer.

4.3 RAM Backup Mode

In RAM backup mode, the M34519T-MCU operates differently from the actual MCUs. Although the actual MCU enters RAM backup mode depending on a combination of instructions EPOF and POF, the M34519T-MCU is placed in RAM backup mode by executing instruction POF only. Instruction EPOF has no effect on the M34519T-MCU.

4.4 Port I/O Timings

(1) Port input timings

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

(2) Port output timings

When using the M34519T-MCU, output timings are different from those of the actual MCUs, because the following ports that are configured with the port emulation circuits.

• Ports D0--D5

• Ports P00--P03

• Ports P10--P13 With the actual MCUs, changes occur at the beginning of the T3 state of an output instruction.

With the M34519T-MCU, changes occur at the beginning of the T2 state of the next output instruction. Figure 4.2 shows the port output timings of the actual MCUs and M34519T-MCU. For the other ports, the output timings are the same as with the actual MCUs.

4.5 A-D Converter

For the M34519T-MCU, its voltage is fixed at 3 V or 5 V. Therefore, because of the difference of voltage, the results of its A/D conversions are slightly different from the theoretical values. And, some characteristics are different from those of actual MCUs, because a flat cable and pitch converter board and other devices are used between the evaluation MCU and target system.

To change a clock frequency, attach the necessary parts to the included oscillator circuit board OSC-2. For details about the oscillation circuit constant, consult your oscillator manufacturer.

4.7 Real-time Capability of the Timer

The M34519T-MCU has its internal clock operating even during emulation, so that the timer values keep changing.

Mode

Frequency

6.0 MHz or less

4.4 MHz or less

Examples: (1) When single-stepping the program

(2) When registers or internal RAM are referenced or modified

4.8 Pullup Transistor Control

Because the M34519T-MCU has an emulation circuit present in ports P0 and P1, you cannot use the MCU's internal pullup transistors. Therefore, the M34519T-MCU controls on/off of external pullup resistors by decoding the pullup control register transfer instructions (TPU0A and TPU1A).

The M34519T-MCU contains 150kΩ pullup resistors for use with the 4518, 4519, 4583 and 4584 Groups. If these pullup resistors need to be changed, replace the RA5 resistor array.

( 26 / 36 )

4.9 Program Execution (G, GB)

The PC4504 and M34519T-MCU's hardware is subject to the following restrictions with respect to the operation of the program execution commands (G and GB).

(1) Continuous description of instructions

Hardware breakpoints 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 4.3.)

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 4.4.)

Program example 4.3

LA 0

POINT: LA 1 ; Continuous description of instructions

LA 2

POINT+2: XAM 3

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

Program example 4.4

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.

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

In cases when a skip instruction skips the next instruction, a breakpoint set in the skipped instruction does not cause execution to halt. (See Program examples 4.5 and 4.6.)

Program example 4.5

LXY 0,0

SZD POINT: B jmp_adr ; Skips when D(0)=0 POINTA: TAM 0

•

If a breakpoint is set at address POINT, the program stops before executing the instruction at POINT when D(0)=1, but does not stop running when D(0)=0 because the instruction at POINT is skipped. To stop the program immediately after executing a skip instruction, be sure to set a breakpoint at both POINT and POINT_A.

Program example 4.6

RC 0,0

INY POINT: TABP ; Skips when D(0)=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.

External trigger signals of trace points and break points use the same signals. The input characteristics of external trigger signals are shown in Table 4.4 below. See the table before using external trigger signals.

4.11 Other Precautions

With the M34519T-MCU, you cannot evaluate systems that use some functions as described below. In such a case, therefore, the system needs to be evaluated using an evaluation-purpose MCU (OTP version).

(1) Because an emulation circuit exists in the RESET pin, systems that use RESET output cannot be

evaluated.

(2) Because the M34519T-MCU has its power supply voltage fixed at 3 V or 5 V, systems that use

a power-down detect function cannot be evaluated. Therefore, results of A-D conversions may be different from expected values.

(3) Power-on reset operation cannot be verified. (4) Because the M34519T-MCU is clocked by the system clock on the board, its clock source cannot

be changed to an on-chip oscillator, CR or crystal oscillator. When using an emulator, do not use the CMCK, CRCK and CYCK instructions in a program.
