(1) 8-bit timer H compare register 0n (CMP0n)
(2) 8-bit timer H compare register 1n (CMP1n)
CMP1n in carrier generator mode. The timer count value is cleared at the same time. If the CMP1n value is rewritten
during timer operation, transferring is performed at the timing at which the count value and CMP1n value match. If the
transfer timing and writing from CPU to CMP1n conflict, transfer is not performed.

CMP1n can be rewritten during timer count operation.
An interrupt request signal (INTTMHn) is generated if the timer count value and CMP1n value match after setting
Caution In the PWM output mode and carrier generator mode, be sure to set CMP1n when starting the
Remark n = 0, 1
This register can be read/written by an 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
Caution CMP0n cannot be rewritten during timer count operation.
This register can be read/written by an 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
timer count operation (TMHEn = 1) after the timer count operation was stopped (TMHEn = 0) (be
sure to set again even if setting the same value to CMP1n).
