12.2.3
TSTR2 is an 8-bit readable/writable register that specifies whether the channel 3 and 4 timer
counters (TCNT) are operated or stopped.
TSTR2 is initialized to H'00 by a power-on reset. TSTR retain their contents in standby mode.
When standby mode is entered when the value of either STR3 or STR4 is 1, the count halts when
the peripheral module clock stops and restarts when the clock supply is resumed.
Bits 7 to 2—Reserved: These bits are always read as 0. A write to these bits is invalid, but the
write value should always be 0.
Bit 1—Counter Start 4 (STR4): Specifies whether timer counter 4 (TCNT4) is operated or
stopped.
Bit 1: STR4
