Name
Function
Function except a port function
Power source
Apply voltage of 4.0 to 5.5 V to VCC, and 0 V to VSS.
Applies voltage supplied to pull-down resistors of ports P0, P1, P20–P23, P3, and P9.
Reference voltage input pin for A-D converter and D-A converter
GND input pin for A-D converter and D-A converter
Connect AVSS to VSS.
Input and output pins for the main clock generating circuit
Feedback resistor is built in between XIN pin and XOUT pin.
Connect a ceramic resonator or a quartz-crystal oscillator between the XIN pin and XOUT pin to
set oscillation frequency.
If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin
open.
This clock is used as the oscillating source of system clock.
8-bit output port
This port builds in pull-down resistor between
port P0 and the VEE pin.
At reset this port is set to VEE level.
