Selection Method and Pin Functions
The pin function is switched as shown below according to the combination of
bit C/A in the SCI2 SMR, bits CKE0 and CKE1 in SCR, and bits IRQPAS and
P52DDR.
Note: * IRQ
The pin function is switched as shown below according to the combination of
bit RE in the SCI2 SCR, and bits IRQPAS and P51DDR.
Note: * IRQ
The pin function is switched as shown below according to the combination of
