TSYR is an 8-bit readable/writable register that selects independent operation or synchronous
operation for the channel 0 to 4 TCNT counters. A channel performs synchronous operation when
the corresponding bit in TSYR is set to 1.
TSYR is initialized to H'00 by a reset, and in hardware standby mode.
Bits 7 and 6—Reserved: Should always be written with 0.
Bits 5 to 0—Timer Synchro 5 to 0 (SYNC5 to SYNC0): These bits select whether operation is
independent of or synchronized with other channels.
When synchronous operation is selected, synchronous presetting of multiple channels *
synchronous clearing through counter clearing on another channel *
Notes: 1. To set synchronous operation, the SYNC bits for at least two channels must be set to 1.

2. To set synchronous clearing, in addition to the SYNC bit , the TCNT clearing source
Timer Synchro Register (TSYR)
must also be set by means of bits CCLR2 to CCLR0 in TCR.
Description
TCNTn operates independently (TCNT presetting/clearing is unrelated to
other channels)
TCNTn performs synchronous operation
TCNT synchronous presetting/synchronous clearing is possible
