PIN DESCRIPTION
Functions
Name
Pin
Apply voltage of 2.7 V – 5.5 V to Vcc, and 0 V to Vss.
In the flash memory version, apply voltage of 4.0 V – 5.5 V to Vcc, and 0 V to Vss
This pin controls the operation mode of the chip.
Normally connected to VSS.
In the flash memory version, this becomes 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 CMOS 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.
Pull-up control is enabled in a bit unit.
P20–P27 are enabled to output large current for LED drive.
8-bit CMOS I/O port.
I/O direction register allows each pin to be individually
programmed as either input or output.
P30, P31, P34–P37 are CMOS 3-state output structure.
P32, P33 are N-channel open-drain output structure.
Pull-up control of P30, P31, P34–P37 is enabled in a bit
unit.
