Section 10 16-Bit Timer Pulse Unit (TPU)
10.2.8
TSTR is an 8-bit readable/writable register that selects operation/stoppage for channels 0 to 5.
TSTR is initialized to H'00 by a reset, and in hardware standby mode.
When setting the operating mode in TMDR or the TCNT count clock in TCR, TCNT counter
operation should first be stopped.
Bits 7 and 6—Reserved: Should always be written with 0.
Bits 5 to 0—Counter Start 5 to 0 (CST5 to CST0): These bits select operation or stoppage for
TCNT.

the 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.
