(3) Capture/compare control register 2 (CRC2)
Remark The register names in the 8-bit operating mode are shown in this figure. In the 16-bit operating mode, the
CRC2
The CRC2 specifies the enabling condition for a timer register 2 (TM2/TM2W) clear operation by the capture/compare
register (CR21/CR21W) or the capture register (CR22/CR22W) and the timer output (TO2/TO3) mode.
CRC2 can be read or written with an 8-bit manipulation instruction. The format of the CRC2 is shown in Figure 10-
4.
RESET input clears CRC2 to 10H.
MOD1
register names TM2, CR20, CR21, and CR22 are TM2W, CR20W, CR21W, and CR22W, respectively.
