(2) Capture/compare control register 00 (CRC00)
Remark
This register controls the operation of the 16-bit capture/compare registers (CR000, CR010).
CRC00 is set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets the value of CRC00 to 00H.
Note When the CRC001 bit value is 1, capture is not performed if both the rising and falling edges have been
Cautions 1. The timer operation must be stopped before setting CRC00.
