15.3.1.1 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
monitor mode, but the pin functions will be determined by the settings in the configuration registers (see
Chapter 5 Configuration Register
BIL instructions will read the IRQ pin state only if IRQEN is set in the CONFIG2 register.
If monitor mode was entered with V
IRQ.
15.3.1.2 Forced Monitor Mode
If entering monitor mode without high voltage on IRQ, then startup port pin requirements and conditions,
(PTA1/PTA4) are not in effect. This is to reduce circuit requirements when performing in-circuit
programming.
