PIN DESCRIPTION
Functions
Name
Pin
•Apply voltage of 2.7 V – 5.5 V to Vcc, and 0 V to Vss.
•This pin controls the operation mode of the chip.
•Normally connected 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.
•P13 to P17 (5 bits) are enabled to output large current for LED drive.
•8-bit CMOS I/O port.
