4. PIN DESCRIPTION
SYMBOL
EA
TYPE
DESCRIPTIONS
EXTERNAL ACCESS ENABLE: This pin forces the processor to execute the
I external ROM. The ROM address and data will not be presented on the bus if
the EA pin is high.

XTAL2

P0.0P0.7

P4.0P4.7
PROGRAM STORE ENABLE: PSEN enables the external ROM data in the
O H Port 0 address/data bus. When internal ROM access is performed, no PSEN
strobe signal outputs originate from this pin.
ADDRESS LATCH ENABLE: ALE is used to enable the address latch that
O H separates the address from the data on Port 0. ALE runs at 1/6th of the
oscillator frequency.
IL
RESET: A high on this pin for two machine cycles while the oscillator is
running resets the device.
I
CRYSTAL 1: This is the crystal oscillator input. This pin may be driven by an
external clock.
O CRYSTAL 2: This is the crystal oscillator output. It is the inversion of XTAL1.
I GROUND: ground potential.
I POWER SUPPLY: Supply voltage for operation.
I/O D PORT 0: Function is the same as that of standard 8052.
I/O H PORT 1: Function is the same as that of standard 8052.
I/O H
PORT 2: Port 2 is a bi-directional I/O port with internal pull-ups. This port also
provides the upper address bits for accesses to external memory. The P2.6
and P2.7 also provide the alternate function REBOOT which is H/W reboot
from LD flash.
I/O H PORT 3: Function is the same as that of the standard 8052.
PORT 4: A bi-directional I/O. The P4.3 also provide the alternate function
I/O H REBOOT which is H/W reboot from LD flash.
* Note: TYPE I: input, O: output, I/O: bi-directional, H: pull-high, L: pull-low, D: open drain

BIT NAME
FUNCTION
00: Mode 0. P4.3 is a general purpose I/O port which is the same as Port1.
01: Mode 1. P4.3 is a Read Strobe signal for chip select purpose. The address
range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
7, 6 P43FUN1 10: Mode 2. P4.3 is a Write Strobe signal for chip select purpose. The address
P43FUN0
range depends on the SFR P43AH, P43AL, P43CMP1 and P43CMP0.
11: Mode 3. P4.3 is a Read/Write Strobe signal for chip select purpose. The
address range depends on the SFR P43AH, P43AL, P43CMP1, and
P43CMP0.
