TCNT cleared by counter clearing for another
channel performing synchronous clearing/
synchronous operation*¹
Notes: 1. Synchronous operation is set 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.

Notes: 1. Synchronous operation is selected by setting the SYNC bit in TSYR to 1.
2. Bit 7 is reserved in channels 1 and 2. It is always read as 0 and cannot be modified.
