25. 16-Bit Timer Pulse Unit (TPUa)
25.2.9
Timer Synchronous Register (TSYR)
Note 1. To set synchronous operation, the SYNCn bit (n = 0 to 5) for at least two channels must be set to 1. To set synchronous
clearing, the TCNT clearing source must also be set by the TCR.CCLR[2:0] bits in addition to the SYNCn bit.
TPU.TSYR selects independent operation or synchronous operation for TCNT of TPU0 to TPU5.
SYNCn Bit (Timer Synchronization n) (n = 0 to 5)
This bit selects whether the TCNT operation is independent of or synchronized with TCNT of other channels.
When synchronous operation is selected, synchronous setting of multiple TCNT and synchronous clearing through
counter clearing on another channel are possible.
