10.2.2 Timer Synchro Register (TSNC)
TSNC is an 8-bit readable/writable register that selects whether channels 0 to 4 operate
independently or synchronously. Channels are synchronized by setting the corresponding bits to 1.

channels 4 to 0
TSNC is initialized to H'E0 by a reset and in standby mode.
Bits 7 to 5—Reserved: Read-only bits, always read as 1.
Bit 4—Timer Sync 4 (SYNC4): Selects whether channel 4 operates independently or
synchronously.
Bit 4
SYNC4 Description
0
Channel 4’s timer counter (TCNT4) operates independently
TCNT4 is preset and cleared independently of other channels
1
Channel 4 operates synchronously
TCNT4 can be synchronously preset and cleared
