PIN DESCRIPTION
Functions
Name
Pin
Apply voltage of 3.0 V ±10 % to Vcc, and 0 V to Vss.
Connected to VSS.
In the flash memory version, this pin functions as the VPP power source input pin.
Reference voltage input pin for A-D and D-A converters.
Analog power source input pin for A-D and D-A converters.
Connect to VSS.
Reset input pin for active “L”.
Input and output pins for the clock generating circuit.
Connect a ceramic resonator or quartz-crystal oscillator between the XIN and XOUT pins to set
the oscillation frequency.
When an external clock is used, connect the clock source to the XIN pin and leave the XOUT
pin open.
8-bit I/O port.
I/O direction register allows each pin to be individually programmed as either input or output.
CMOS compatible input level.
CMOS 3-state output structure or N-channel open-drain output structure.
8-bit I/O port.
I/O direction register allows each pin to be individually programmed as either input or output.
CMOS compatible input level.
CMOS 3-state output structure or N-channel open-drain output structure.
8-bit I/O port.
I/O direction register allows each pin to be individually
programmed as either input or output.
CMOS compatible input level.
CMOS 3-state output structure.
P24 to P27 (4 bits) are enabled to output large current for LED drive.
8-bit I/O port.
I/O direction register allows each pin to be individually
programmed as either input or output.
CMOS compatible input level.
CMOS 3-state output structure.
These pins function as key-on wake-up and compara-
tor input.
These pins are enabled to control pull-up.
