Bit 0—Timer Clock Pin Control (TCOE): Specifies whether timer clock pin TCLK is used as
the external clock or input capture control input pin, or as the on-chip RTC output clock output
pin.

Note:
12.2.2
TSTR is an 8-bit readable/writable register that specifies whether the channel 0–2 timer counters
(TCNT) are operated or stopped.
TSTR is initialized to H'00 by a power-on or manual reset. In module standby mode, TSTR is not
initialized when the input clock selected by each channel is the on-chip RTC output clock
(RTCCLK), and is initialized only when the input clock is the external clock (TCLK) or internal
clock (Pck).
Bits 7 to 3—Reserved: These bits are always read as 0. A write to these bits is invalid, but the
write value should always be 0.
Bit 2—Counter Start 2 (STR2): Specifies whether timer counter 2 (TCNT2) is operated or
stopped.
Bit 2: STR2
