12.2 Register Descriptions
12.2.1 Timer Output Control Register (TOCR)
TOCR is an 8-bit readable/writable register that specifies whether external pin TCLK is used as
the external clock or input capture control input pin, or as the on-chip RTC output clock output
pin.
TOCR is initialized to H'00 by a power-on or manual reset, but is not initialized in standby mode.
