Note:

Internal clock edge selection is valid only when the input clock is ø/4 or slower. This
setting is ignored when the input clock is ø/1 or an overflow or underflow in another
channel is selected.

Note:
1. Synchronous operation setting is performed by setting the SYNC bit in TSYR to 1.
2. When TGRC or TGRD is used as a buffer register, TCNT is not cleared because the buffer
register setting has priority, and compare match/input capture does not occur.
