TSTR is an 8-bit readable/writable register that selects operation/stoppage for channels 0 to 2.

TSTR is initialized to H'00 by a reset, and in hardware standby mode.

TCNT counter operation should be stopped when setting the operating mode in TMDR or the

TCNT count clock in TCR.

Bits 7 and 3—Reserved: Should always be written with 0.

Bits 2 to 0—Counter Start 2 to 0 (CST2 to CST0): These bits select operation or stoppage for

TCNT.

Description

TCNTn count operation is stopped

(Initial value)

TCNTn performs count operation

n = 2 to 0

Note:

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