CHAPTER 10 TIMER/EVENT COUNTER 1
(3) Capture/compare control register 1 (CRC1)
CRC1 specifies the operation of the capture/compare register (CR11/CR11W) and the enabling condition for a timer counter
1 (TM1/TM1W) clear operation.
CRC1 can be read or written to with an 8-bit manipulation instruction. The format of CRC1 is shown in Figure 10-4.
RESET input clears CRC1 to 00H.
