Pin function
P42/IRQ2/TMO0/ExMCDAT/ExMCRxD
The pin function is switched as shown below according to the combination of the MCIF
operating mode, the OS3 to OS0 bits in TCSR of TMR_1, and the P42DDR bit.
When the ISS2 bit in ISSR is cleared to 0 and the IRQ2E bit in IER of the interrupt controller
is set to 1, this pin can be used as the IRQ2 input pin. To use this pin as the IRQ2 input pin,
clear the P42DDR bit to 0.
