• Manufacturer Part Number: upd78f0103hmca1-5a4-a
• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

(1) 8-bit timer H compare register 0n (CMP0n)
(2) 8-bit timer H compare register 1n (CMP1n)
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.
If the CMP1n value is rewritten during timer operation, transfer is performed at the timing at which the count value
Caution In the PWM output mode be sure to set CMP1n when starting the timer count operation (TMHEn =

This register can be read/written by an 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
