12.3.1
TOCR is an 8-bit read/write register that selects whether to use the external TCLK pin as an
external clock or an input capture control usage input pin, or an output pin for the on-chip RTC
output clock. TOCR is initialized to H'00 by a power-on reset or manual reset, but is not initialized
in standby mode.

Selects use of the timer clock pin (TCLK) as an
external clock output pin or input pin for input capture
control for the on-chip timer, or as an output pin for
the on-chip RTC output clock. As the TCLK pin is
multiplexed as the PTE6 pin, when the TCLK pin is
used, bits PE6MD1 and PH7MD0 in the PECR
register should be set to 00 (Other function).
