(4) Prescaler mode register 00 (PRM00)
154
PRM00 is the register that sets the TM00 count clock and TI000 and TI010 pin input valid edges.
Rewriting PRM00 is prohibited during operation (when TMC003 and TMC002 = other than 00).
PRM00 can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PRM00 to 00H.
Cautions 1. Do not apply the following setting when setting the PRM001 and PRM000 bits to 11 (to
