Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
10.3.15 Timer Start Register (TSTR)
TSTR is an 8-bit readable/writable register that selects operation/stoppage of TCNT for channels 0
to 4.
TSTR_5 is an 8-bit readable/writable register that selects operation/stoppage of TCNTU_5,
TCNTV_5, and TCNTW_5 for channel 5.

Description
Counter Start 4 and 3
These bits select operation or stoppage for TCNT.
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.
0: TCNT_4 and TCNT_3 count operation is stopped
1: TCNT_4 and TCNT_3 performs count operation
Reserved
These bits are always read as 0. The write value should
always be 0.
