17.3.1.1 Normal Monitor Mode
RST and OSC1 functions will be active on the PTA3 and PTA5 pins respectively as long as V
applied to the IRQ pin. If the IRQ pin is lowered (no longer V

Chapter 5 Configuration Register
BIL instructions will read the IRQ pin state only if IRQEN is set in the CONFIG2 register.
