2.1 VDD, VSS, and EVSS
Power is supplied to the MCU through VDD and VSS. VSS is the power supply, and
VSS is ground. EVSS, available on the 44-pin PLCC, is an additional ground pin that
must be grounded with VSS. The MCU operates from a single 5-volt (nominal) power
supply. Very fast signal transitions occur on the MCU pins. The short rise and fall times
place high, short duration current demands on the power supply. To prevent noise
problems, provide good power supply bypassing at the MCU. Also, use bypass capac-
itors that have good high-frequency characteristics and situate them as close to the
MCU as possible. Bypass requirements vary, depending on how heavily the MCU pins
are loaded.
2.2 Reset (RESET)
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 COP watchdog circuit. The
CPU distinguishes between internal and external reset conditions by sensing whether
the reset pin rises to a logic one in less than two E-clock cycles after a reset has oc-
curred. It is not advisable to connect an external resistor-capacitor (RC) power-up de-
lay circuit to the reset pin of M68HC11 devices because the circuit charge time
