Pin function
According to the combination of the CLOE bit in TCONRO of the timer connection_0 and the
PA4DDR bit, the pin function is switched as shown below.
When the ICICE bit in TIER of the FRT_0 is set to 1, this pin functions as the FTIC_0 input
pin.
According to the combination of the CBOE bit in TCONRO of the timer connection_0, the
OEB bit in TOCR of the FRT_0, and the PA3DDR bit, the pin function is switched as shown
below.
