REJ10J1005-0200 Rev.2.00 April 1, 2007
IMPORTANT
Note on Protect Resistor:
z A protect is not canceled when protect register bit 2 (PRC2), which enables writing in the port P9 direction
register and the function select register A3, is changed with the below procedure.
(1) Step execution of an instruction setting ("1") PRC2
(2) Setting a break point from an instruction setting ("1") PRC2 to where the port P9 direction register or the
function select register A3 is set
(3) Setting ("1") PRC2 from the dump window or script window during user program execution
Note on Memory Access:
z When setting memory expansion mode as a processor mode, it may be changed to memory expansion mode
temporarily before the user program itself changes from single-chip mode to memory expansion mode.
Take due consideration on this phenomenon in the following cases:
(1) Immediately before executing the program after setting a software break
(2) Immediately after stopping the program when a software break is set
Note on Voltage Detect Circuit:
z As the power voltage cannot be changed after powering on the user system, the voltage detect circuit (voltage
down detect interrupt and hardware reset 2) cannot be used with this product.
Note on Page Mode Control Function:
z When using the page mode control function for a ROM-less version of the M32C/84 Group, in a cycle for an
area (excluding the emulation memory) written in word, the following emulator function does not operate
normally.
- Real-time RAM monitor
- Event detection
- Real-time trace display
This precaution only needs to be observed when using an emulator, and do not apply for the actual MCU.
