CHAPTER 9 TIMER/EVENT COUNTER 0
9.7 Basic Operation of Output Control Circuit
The output control circuit controls the timer output pin (TO0/TO1) levels by means of overflow signals or match signals from
the compare registers (CR00, CR01). The operation of the output control circuit is determined by the timer output control register
(TOC), capture/compare control register 0 (CRC0), and the one-shot pulse output control register (OSPC) (see Table 9-5).
When TO0, TO1 signals are output to a pin, the relevant pin must be in control mode in the port 3 mode register (PMC3).
