Remarks 1. If both CR00n and CR01n are used as capture registers in the free-running timer mode, the TO0n
2. n = 0:
output level is not inverted.
However, it can be inverted each time the valid edge of the TI00n pin is detected if bit 1 (TMC0n1)
of 16-bit timer mode control register 0n (TMC0n) is set to 1.
