Section 10 16-Bit Integrated Timer Unit (ITU)
Bit 1—Counter Start 1 (STR1): Starts and stops timer counter 1 (TCNT1).
Bit 0—Counter Start 0 (STR0): Starts and stops timer counter 0 (TCNT0).
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.
Bit
Initial value
Read/Write
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.
