CHAPTER 10 TIMER/COUNTER FUNCTION (REAL-TIME PULSE UNIT)
(5) External pulse output
Timer C has four timer output pins (TO0n).
An external pulse output (TO0n) is generated when a match of the two compare registers (CCCn0 and
CCCn1) and the TMCn register is detected.
If a match is detected when the TMCn count value and the CCCn0 value are compared, the output level of
the TO0n pin is set. Also, if a match is detected when the TMCn count value and the CCCn1 value are
compared, the output level of the TO0n pin is reset.
The output level of the TO0n pin can be specified by the TMCCn1 register.
