  1. There are following limitations when using the emulator.
    • (1) When using the emulator, the I/O port P8_5 is an N-channel Open-drain output. A 510kΩ pull-up resistor is connected to the P8_5 in the emulator. Please refer to R0E535M00MCU00 release notes and user's manual for details.
      • a)  M16C/5L, M16C/56 Groups (I/O port : CMOS output)
        When using the I/O port P8_5 as an output port, an external pull-up resistor of the VCC level is needed on the user system.
      • b)  M16C/5M, M16C/57 Group (I/O port : N-channel Open-drain output)
        Set the value of the the pull-up resistor for the I/O port P8_5 up to the VCC level.
    • (2) The functions of the multi-master I2C-bus interface and LIN module have limitations when using the emulator. Please see  Release notes and  User's manual for further details.
