The OSC1 and OSC2 pins are the connections for the on-chip oscillator
circuit. The OSC1 pin contains a schmitt-trigger and a spike filter for
improved EMC performance. 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. A schmitt-trigger and a spike filter
is associated with this pin so that the device is more robust to EMC
noise.This pin also contains an internal pullup resistor. See
System Integration Module
IRQ is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor. See
CGMXFC is an external filter capacitor connection for the CGM. See
