7.3.8 Basic Operation of Output Control Circuit
The output control circuit controls the levels of the timer outputs (TO2, TO3) according to the coincidence signal
from the compare registers. The operation of the output control circuit is determined by timer output control
register (TOC) and capture/compare control register 2 (CRC2). (See Table 7-15.) Before a timer output (TO0 or TO1)
signal can be output on a pin, the pin must be placed in the control mode by the PMC3 register.
