Selection Method and Pin Functions
The pin function is switched as shown below according to bit P83DDR.
The pin function is switched as shown below according to the combination of
operating mode, bit SDE in SYSCR2, and bit P82DDR.
The pin function is switched as shown below according to the combination of
operating mode, bit CS2E in SYSCR, bit FGA20E in HICR of the HIF, and bit
P81DDR.
This pin should be used as the GA20 output pin or CS2 input pin only in mode
2 or 3 (EXPE = 0).
The pin function is switched as shown below according to the combination of
operating mode and bit P80DDR.
