10.2.2
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.
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
