11.8 Basic Operation of Output Control Circuit
The output control circuit controls the timer output pins (TO2/TO3) level by means of match signals from the compare
register (CR22). The operation of the output control circuit is determined by the timer output control register (TOC) and
capture/compare control register 2 (CRC2) (see Table 11-5). When TO2/TO3 signal is output to a pin, the relevant pin
must be in control mode in the port 3 mode register (PMC3).
