This section lists and describes the signals that connect off chip.
11.2.1
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
11.2.2
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.
