The relationship between register setting values and pin functions are as follows.
•
P47 to P44
The pin function is switched as shown below according to the P4nDDR bit and the P4nNCE bit.
When the ISSn bit in ISSR is cleared to 0 and the IRQnE bit in IER of the interrupt controller is
set to 1, the pin can be used as the
IRQn
input pin. To use as the
IRQn
input pin, clear the
P4nDDR bit to 0.
