Function
Applies power voltage
Connected to ground
Used for factory testing only; connect
this pin to V
Resets the MCU
Input/output pins for the internal
oscillator circuit; connect them to a
crystal, ceramic, or external oscillator
circuit
Used for a 32.768-kHz crystal for
clock purposes; if not used, fix X1 to
V
Input/output ports addressed by
individual bits; pins D
current pins that can each supply up
to 15 mA
Input ports addressable by individual
bits
Input/output ports addressable in 4-
bit units
Input pins for external interrupts
Serial interface clock input/output pin
Serial interface receive data input pin
Serial interface transmit data output
pin
Buzzer signal output pin
Power pins for LCD driver; can be left
open in operation because they are
connected by internal voltage division
resistors (except for HD404324U,
HD404326U, HD404328U and
HD4074329U) Voltage conditions
