The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit.
A logic zero on the RST pin forces the MCU to a known start-up state.
RST is bidirectional, allowing a reset of the entire system. It is driven low
when any internal reset source is asserted. The RST pin contains an
internal pullup device to V
Module
IRQ is an asynchronous external interrupt pin. IRQ is also the pin to
enter Monitor mode. The IRQ pin contains a software configurable pullup
device to V
