8-bit compare register 0n (CR0n)
This is an 8-bit register that compares the value set to CR0n with the 8-bit timer counter 0n (TM0n) count
value, and if they match, an interrupt request (INTTM0n) is generated.
CR0n is set using an 8-bit memory manipulation instruction. Values from 00H to FFH can be set.
RESET input makes CR0n undefined.
Caution Be sure to stop the operation of the timer before rewriting CR0n. If CR0n is rewritten while
Remark
8-bit timer counter 0n (TM0n)
This is an 8-bit register that counts pulses.
TM0n is read using an 8-bit memory manipulation instruction.
RESET input sets TM0n to 00H.
