WR/DS/SDI 84 J14 I
Write Enable/Data Strobe/Serial Data
Intel Parallel Host Mode
- This pin, “WR”, functions as
a write enable.
Motorola Parallel Host Mode
- This pin, “DS“, functions as
a data strobe input.
Serial Host Mode
- This pin, “SDI”, functions as the serial
data input.
Hardware Mode
- This pin is not used and should be con-
nected to ground.
RD
/RW 85 J13 I
Read Enable/Read/Write
Intel Parallel Host Mode
- This pin, “RD”, functions as a
read enable.
Motorola Parallel Host Mode
- This pin, “R/W”, functions
as the read/write input signal.
Hardware Mode

nected to ground.
ALE/AS
/SCLK 86 J12 I
Address Latch Enable/Address Strobe/Serial Clock
Intel Parallel Host Mode
- This pin, “ALE”, functions as the
Address Latch Enable when configured for multiplexed ad-
dress/data operation.
Motorola Parallel Host Mode
- This pin, “AS”, functions as
the active “low” address strobe when configured for multi-
plexed address/data operation.
Serial Host Mode
- This pin, “SCLK”, is the serial clock
used for data I/O on SDI and SDO.
Hardware Mode
- This pin is not used and should be con-
nected to ground.
