Technical Data
32
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 startup 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 that is always activated, even when the reset pin is pulled low.
See
IRQ is an asynchronous external interrupt pin. This pin contains an
internal pullup resistor that is always activated, even when the reset pin
is pulled low. See
V
clock generator module (CGM). Decoupling of these pins should be as
per the digital supply. See
