MC68HC912BD32 power and ground pins are described below and
summarized in
Power is supplied to the MCU through V
transitions place high, short-duration current demands on the power
supply, use bypass capacitors with high-frequency characteristics and
place them as close to the MCU as possible. Bypass requirements
depend on how heavily the MCU pins are loaded.
External power and ground for I/O drivers. Because fast signal
transitions place high, short-duration current demands on the power
supply, use bypass capacitors with high-frequency characteristics and
place them as close to the MCU as possible. Bypass requirements
depend on how heavily the MCU pins are loaded.
Provides operating voltage and ground for the analog-to-digital
converter. This allows the supply voltage to the A/D to be bypassed
independently.
Flash EEPROM programming voltage and supply voltage during normal
operation.
