Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bit CLOE in TCONRO of the timer connection function and bit P64DDR.
This pin can always be used as the FTIC, KIN4, or CIN4 input pin.
This pin can always be used as the FTIB, KIN3, CIN3, or VFBACKI input pin.
This pin can always be used as the FTIA, TMIY, KIN2, CIN2, or VSYNCI input
pin.
The pin function is switched as shown below according to the combination of
bit OEA in TOCR of the FRT, bit VOE in TCONRO of the timer connection
function, and bit P61DDR.
When this pin is used as the VSYNCO pin, bit OEA in TOCR of the FRT must
be cleared to 0.
This pin can always be used as the KIN1 or CIN1 input pin.
