P3.2 and P3.3 also act as external interrupt

sources, alias INT0 and INT1.

P3.4 and P3.5 also act as event sources for

timer0 and timer1 individually, alias T0 and T1.

P3.6 also acts as write signal while access to

external memory, alias /WR.

P3.7 also acts as read signal while access to

external memory, alias /RD.

P4.0

BU Port4 is extended I/O ports such like Port1. It can

be available only on 44L-PLCC and 44L-PQFP

package.

P4.1

P4.2 (/INT3)

P4.3 (/INT2)

RESET

IS A high on this pin for at least two machine cycles

will reset the device.

ALE

Output pulse for latching the low byte of address

during accesses to external memory.

/PSEN

/EA

The read strobe to external program memory, low

active.

EA must be kept at low to enable the device to

fetch program code from external flash memory.

An internal pull-up resistance has been

embedded in this pin.

XTAL1

XTAL2

VDD

Input to the inverting oscillator amplifier.

Output from the inverting amplifier.

Power Supply

VSS

Ground
