NAME AND FUNCTION
Ground:
0 V reference.
Power Supply:
This is the power supply voltage for normal, idle, and power-down
operation.
Port 0:
Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to
them float and can be used as high-impedance inputs. Port 0 is also the multiplexed
low-order address and data bus during accesses to external program and data memory.
In this application, it uses strong internal pull-ups when emitting 1s. Port 0 also outputs
the code bytes during program verification and received code bytes during Flash
programming. External pull-ups are required during program verification.
Port 1:
Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. Port 1 pins that have
1s written to them are pulled high by the internal pull-ups and can be used as inputs. As
inputs, port 1 pins that are externally pulled low will source current because of the
internal pull-ups. (See DC Electrical Characteristics: I
). Port 1 also receives the
low-order address byte during program memory verification. Alternate functions for Port 1
include:
T2 (P1.0):
Timer/Counter 2 external count input/clockout (see Programmable
Clock-Out)
T2EX (P1.1):
Timer/Counter 2 Reload/Capture/Direction control
Port 2:
Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that have
1s written to them are pulled high by the internal pull-ups and can be used as inputs. As
inputs, port 2 pins that are externally being pulled low will source current because of the
internal pull-ups. (See DC Electrical Characteristics: I
). Port 2 emits the high-order
address byte during fetches from external program memory and during accesses to
external data memory that use 16-bit addresses (MOVX @DPTR). In this application, it
uses strong internal pull-ups when emitting 1s. During accesses to external data memory
that use 8-bit addresses (MOV @Ri), port 2 emits the contents of the P2 special function
register. Some Port 2 pins receive the high order address bits during Flash programming
and verification.
Port 3:
Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have
1s written to them are pulled high by the internal pull-ups and can be used as inputs. As
inputs, port 3 pins that are externally being pulled low will source current because of the
pull-ups. (See DC Electrical Characteristics: I
IL
). Port 3 also serves the special features
of the 80C51 family, as listed below:
RxD (P3.0):
Serial input port
TxD (P3.1):
Serial output port
INT0 (P3.2):
External interrupt
INT1 (P3.3):
External interrupt
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
Reset:
A high on this pin for two machine cycles while the oscillator is running, resets the
device. An internal diffused resistor to V
SS
permits a power-on reset using only an
external capacitor to V
CC
.
Address Latch Enable/Program Pulse:
Output pulse for latching the low byte of the
address during an access to external memory. In normal operation, ALE is emitted at a
constant rate of 1/6 (12-clk) or 1/3 (6-clk Mode) the oscillator frequency, and can be used
for external timing or clocking. Note that one ALE pulse is skipped during each access to
external data memory. This pin is also the program pulse input (PROG) during Flash
programming. ALE can be disabled by setting SFR auxiliary.0. With this bit set, ALE will
be active only during a MOVX instruction.
Program Store Enable:
The read strobe to external program memory. When the device
is executing code from the external program memory, PSEN is activated twice each
machine cycle, except that two PSEN activations are skipped during each access to
external data memory. PSEN is not activated during fetches from internal program
memory.
External Access Enable/Programming Supply Voltage:
EA must be externally held low to enable the
device to fetch code fromexternal programmemory locations 0000H to FFFFH. If EA is held high, the device
executes frominternal programmemory. This pin also receives the 5 V / 12 V programmng supply voltage
(V
PP
) during Flash programmng. If security bit 1 is programmed, EA will be internally latched on Reset.
