3.7 How to Replace the MCU For debugging the 4583 and 4584 Group MCUs, it is necessary to replace the evaluation MCU to the included M34584MD-001FP. When replacing the MCU, match the No. 1 pin of the IC socket and that of the MCU as shown in Figure 3.10. Incorrect insertion may cause a fatal damage to the MCU. The M34519M8-001FP is mounted when shipped from the factory. Top view 42 22 M34584MD-001FP 1 21 Figure 3.
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 Item H-level threshold voltage L-level threshold voltage Hysteresis voltage Symbol VP VN VH Voltage Min. Max. VCC = 2.0 V 1.0 V 1.5 V VCC = 4.5 V 2.3 V 3.
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. [Actual MCU] Program example 4.1 Placed in RAM backup mode RC INY EPOF POF • • [M34519T-MCU] Placed in RAM backup mode [Actual MCU] Program example 4.
(3) Port I/O Characteristics With the M34519T-MCU, port I/O characteristics are different from actual MCUs because there are emulation circuits in ports P00--P03, P10--P13 and D0--D5. Table 4.2 lists port I/O characteristics of the M34519T-MCU. Table 4.2 Emulation port I/O characteristics Port Device Item Condition Min. Standard Max. VCC = 2.0 V 1.50 V - - VCC = 4.5 V 3.15 V - - VCC = 2.0 V - - 0.50 V VCC = 4.5 V - - 1.35 V VOL VCC = 4.5 V - 0.35 V 0.5 V IOL VCC = 5.
4.6 System Clock Depending on the supply voltage and operation mode, use one of the following frequencies listed in Table 4.3. Table 4.3 M34519T-MCU operating frequencies Voltage Mode Frequency Divide-by-8 Divide-by-4 6.0 MHz or less 5V Divide-by-2 Through Divide-by-8 Divide-by-4 6.0 MHz or less 3V Divide-by-2 Through 4.4 MHz or less To change a clock frequency, attach the necessary parts to the included oscillator circuit board OSC-2.
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.
