For the 40-pin ATA-Disk Module, power can be supplied either through the pin 20 (not present on standard 40-pin
IDE interface) or through the external power connector provided on the 40-pin ADM. Please see the drawings in
“Physical Dimensions” on page 36 for information.

Name and Functions
A[2:0] are used to select one of the Task File registers.
Data bus
CS1FX#, CS3FX#
I
CS1FX# is the chip select for the task file registers while CS3FX# is used to
select the Alternate Status Register and the Device Control Register.
CSEL signal is a NC to the motherboard. The Master/Slave selection is set by a
jumper. If the jumper is in a Master position, the ADM is addressed as a Master
drive, and if the jumper is in a Slave position, the ADM is addressed as a Slave
drive.
This is an I/O Read strobe generated by the host. This signal gates I/O data
onto the bus from the chip.
The I/O Write strobe pulse is used to clock I/O data into the chip.
This output signal is asserted low when this device is expecting a word data
transfer cycle.
Signal is the active high Interrupt Request to the host.
This input/output is the Pass Diagnostic signal in the Master/Slave hand-
shake protocol.
This input/output is the Disk Active/Slave present signal in the Master/Slave
handshake protocol.
This input pin is the active low hardware reset from the host.

Write protect pin is used to disable Write operation. The 3-position jumper can set
pin 30 as NC, write protected (by connecting to GND), or host selectable (by con-
necting to pin 30 of IDE connector). When the signal on this pin is low, data on the
chip will be write-protected. (See Figure 2-1)
