19. Multi-Function Timer Pulse Unit 3 (MTU3c)
Note 1. Synchronous operation is selected by setting the TSYRA.SYNC bit to 1
Note 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.
Note 1. Synchronous operation is selected by setting the TSYRA.SYNC bit to 1.
Note 2. Bit 7 is reserved in MTU1 and MTU2. It is read as 0. The write value is ignored.
MTU5.TCRU, MTU5.TCRV, MTU5.TCRW
