These pins provides operating voltage (V
the supply voltage to the IPLL to be independently bypassed. Even if IPLL usage is not required V
and V
8.2.2
RESET is an active low bidirectional reset pin. As an input it initializes the MCU asynchronously to a
known start-up state. As an open-drain output it indicates that an system reset (internal to MCU) has been
triggered.
