The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit. See
A logic 0 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. This pin contains an internal pullup
resistor. See
IRQ is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor. See
