Data Sheet

Power is supplied to the MCU through V
(+5 V ±10%) and V
QFP, is an additional ground pin.
An active low bidirectional control signal, RESET, acts as an input to initialize the
MCU to a known startup state. It also acts as an open-drain output to indicate that
an internal failure has been detected in either the clock monitor or computer
operating properly (COP) watchdog circuit. In addition, the state of this pin is one
of the factors governing the selection of BOOT mode.
