12.2.3
TSTR2 is an 8-bit readable/writable register that specifies whether the channels 3−4 timer
counters (TSTR2) run or are stopped.
TSTR2 is initialized to H'00 by a power-on reset and retains its value in standby mode. If standby
mode is entered when the STR3 or STR4 bit is set to 1, counting is halted at the same time as the
peripheral module clock is stopped. Counting is restarted on resumption of the clock-signal
supply.
Bits 7 to 2—Reserved: These bits are always read as 0. Writing to these bits is invalid. If a value
is written to these bits, it should always be 0.
Bit 1—Counter Start 4 (STR4): Specifies whether timer counter 4 (TCNT4) runs or is stopped.
Bit 1: STR4

Bit 0—Counter Start 3 (STR3): Specifies whether timer counter 3 (TCNT3) runs or is stopped.
