Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
operating mode, bit HI12E in SYSCR2, and bit P94DDR.
The pin function is switched as shown below according to the combination of
operating mode, bit HI12E in SYSCR2, and bit P93DDR.
When bit IRQ0E in IER is set to 1, this pin is used as the IRQ0 input pin.
When bit IRQ1E in IER is set to 1, this pin is used as the IRQ1 input pin.
