TSYRA selects independent operation or synchronous operation of TCNT in MTU0 to MTU4.
A channel performs synchronous operation when the corresponding bit in TSYR is set to 1.
SYNCn Bits (Timer Synchronous Operation n) (n = 0, 1, 2, 3, 4)
Each bit selects whether operation is independent of or synchronized with other channels.
When synchronous operation is selected, the TCNT synchronous setting of multiple channels and synchronous clearing
by counter clearing on another channel are possible.
To set synchronous operation, the SYNC bits for at least two channels must be set to 1. To set synchronous clearing, in
addition to the SYNC bit, the TCNT clearing source must also be set by means of the TCR.CCLR[2:0] bits.

Description
0: MTU0.TCNT operates independently (TCNT setting/clearing is not
related to other channels).
1: MTU0.TCNT performs synchronous operation.
(TCNT synchronous setting/synchronous clearing is enabled.)
0: MTU1.TCNT operates independently (TCNT setting/clearing is not
related to other channels).
1: MTU1.TCNT performs synchronous operation.
(TCNT synchronous setting/synchronous clearing is enabled.)
0: MTU2.TCNT operates independently (TCNT setting/clearing is not
related to other channels).
1: MTU2.TCNT performs synchronous operation.
(TCNT synchronous setting/synchronous clearing is enabled.)
These bits are read as 0. The write value should be 0.
0: MTU3.TCNT operates independently (TCNT setting/clearing is not
related to other channels).
1: MTU3.TCNT performs synchronous operation.
(TCNT synchronous setting/synchronous clearing is enabled.)
0: MTU4.TCNT operates independently (TCNT setting/clearing is not
related to other channels).
1: MTU4.TCNT performs synchronous operation.
(TCNT synchronous setting/synchronous clearing is enabled.)
