Section 8 I/O Ports
• P90/IRQ2/ADTRG
The pin function is switched as shown below according to the P90DDR bit.
When the TRGS1 and TRGS0 bits in ADCR are both set to 1, this pin can be used as the
ADTRG input pin.
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.
