A logic 0 on the RST pin forces the MCU to a known startup state. RST
is bidirectional, allowing a reset of the entire system. It is driven low when
any internal reset source is asserted. See
Integration Module
IRQ is an asynchronous external interrupt pin (see
Interrupt
V
clock generator module (CGM). Decoupling of these pins should be as
per the digital supply. See
CGMXFC is an external filter capacitor connection for the CGM. See
