PIN DESCRIPTION
SYMBOL
DESCRIPTIONS
EA
EXTERNAL ACCESS ENABLE
: This pin forces the processor to execute out of
external ROM. It should be kept high to access internal ROM. The ROM address and
data will not be presented on the bus if
EA
pin is high and the program counter is
within on-chip ROM area. Otherwise they will be presented on the bus.
PSEN
PROGRAM STORE ENABLE:
PSEN
enables the external ROM data onto the Port 0
address/ data bus during fetch and MOVC operations. When internal ROM access is
performed, no PSEN strobe signal outputs from this pin. This pin also serves the
alternative function P4.6.
ADDRESS LATCH ENABLE
: ALE is used to enable the address latch that separates
the address from the data on Port 0. This pin also serves the alternative function P4.5
RESET
: A high on this pin for two machine cycles while the oscillator is running resets
the device.
CRYSTAL1
: This is the crystal oscillator input. This pin may be driven by an external
clock.
CRYSTAL2
: This is the crystal oscillator output. It is the inversion of XTAL1.
GROUND
: Ground potential
POWER SUPPLY
: Supply voltage for operation.
P0.0
P0.7
PORT 0
: Port 0 is a bi-directional I/O port which also provides a multiplexed low order
address/data bus during accesses to external memory. The pins of Port 0 can be
individually configured to open-drain or standard port with internal pull-ups.
P1.0
P1.7
PORT 1
: Port 1 is a bi-directional I/O port with internal pull-ups. The bits have alternate
functions which are described below:
INT2
INT9(P1.0
P1.7): External interrupt 2 to 9
P2.0
P2.7
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.
P3.0
P3.7
PORT 3
: Port 3 is a bi-directional I/O port with internal pull-ups. The pins P3.4 to P3.7
can be configured with high sink current which can drive LED displays directly. All bits
have alternate functions, which are described below:
ALE
RST
XTAL1
XTAL2
V
SS
V
DD
INT0 (P3.2) : External Interrupt 0
INT1
(P3.3) : External Interrupt 1
T0(P3.4)
: Timer 0 External Input
T1(P3.5)
: Timer 1 External Input
WR
(P3.6)
: External Data Memory Write Strobe
RD
(P3.7)
: External Data Memory Read Strobe
P4.0
P4.6
PORT 4:
A 6-bit bi-directional I/O port which is bit-addressable. Pins P4.0 to P4.3 are
available on 44-pin PLCC/QFP package. Pins P4.5 and P4.6 are the alternative
function corresponding to ALE and PSEN.
