Section 9 16-Bit Timer Pulse Unit (TPU)
Bits 5 to 0—Counter Start 5 to 0 (CST5 to CST0): These bits select operation or stoppage for
TCNT.

Note: If 0 is written to the CST bit during operation with the TIOC pin designated for output, the
9.2.9
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: Must 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.

counter stops but the TIOC pin output compare output level is retained. If TIOR is written to
when the CST bit is cleared to 0, the pin output level will be changed to the set initial output
value.
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.
