Keypad Input Lines
Holding one of these pins high or low for 24 oscillator periods triggers a
keypad interrupt.

Function
A15:8
I/O
Address Lines
Upper address lines for the external bus.
Multiplexed higher address and data lines for the IDE interface.
P2.7:0
AD7:0
I/O
Address/Data Lines
Multiplexed lower address and data lines for the external memory or the
IDE interface.
P0.7:0
ALE
O
Address Latch Enable Output
ALE signals the start of an external bus cycle and indicates that valid
address information is available on lines A7:0. An external latch is used
to demultiplex the address from address/data bus.

PSEN
I/O
Program Store Enable Output (AT80C51SND1C Only)
This signal is active low during external code fetch or external code
read (MOVC instruction).
-
ISP
I/O
ISP Enable Input (AT89C51SND1C Only)
This signal must be held to GND through a pull-down resistor at the
falling reset to force execution of the internal bootloader.
-
RD
O
Read Signal
Read signal asserted during external data memory read operation.
P3.7
WR
O
Write Signal
Write signal asserted during external data memory write operation.
P3.6
EA(1)(2)
I
External Access Enable (Dice Only)
EA must be externally held low to enable the device to fetch code from
external program memory locations 0000h to FFFFh.

Function
RST
I
Reset Input
Holding this pin high for 64 oscillator periods while the oscillator is
running resets the device. The Port pins are driven to their reset
conditions when a voltage lower than V
IL is applied, whether or not the
oscillator is running.
This pin has an internal pull-down resistor which allows the device to be
reset by connecting a capacitor between this pin and V
DD.
Asserting RST when the chip is in Idle mode or Power-Down mode
returns the chip to normal operation.
-
TST
I
Test Input
Test mode entry signal. This pin must be set to V
DD.
