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 setting the count clock in TCR, first stop the TCNT counter.
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.
Notes: 1. n = 5 to 0

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.
