(2) Capture/compare control register 0 (CRC0)
Address: FF62H
Symbol
CRC0
This register controls the operation of the 16-bit timer capture/compare registers (CR00, CR01).
CRC0 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears CRC0 to 00H.
Note If both the rising and falling edges have been selected as the valid edges of TI00, capture is not performed.
Cautions 1. The timer operation must be stopped before setting CRC0.
2. When the clear & start mode entered on a match between TM0 and CR00 is selected by 16-
3. To ensure the reliability of the capture operation, the capture trigger requires a pulse longer
