Pin function
P57/IRQ15/PWX1
The pin function is switched as shown below according to the combination of the OEB bit in
DACR of PWMX and the P57DDR bit.
When the IRQ15E bit in IER16 of the interrupt controller is set to 1 or the ISS15 bit in ISSR16
is cleared to 0, this pin can be used as the IRQ15 input pin. To use this pin as the IRQ15 input
pin, clear the P57DDR bit to 0.

P5DR stores output data for the port 5 pins that
are used as the general output port.
If a port 5 read is performed while the P5DDR bits
are set to 1, the P5DR values are read. If a port 5
read is performed while the P5DDR bits are
cleared to 0, the pin states are read.
