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 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.

when the CST bit is cleared to 0, the pin output level will be changed to the set initial output
value.
