DATASHEET
This section provides a detailed description of each signal. The signals are arranged in functional
groups according to their associated interface.
The “n” symbol in the signal name indicates that the active, or asserted state occurs when the signal
is at a low voltage level. When “n” is not present before the signal name, the signal is asserted when
at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signal. The term assert, or assertion indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation indicates that a signal is inactive.

CompactFlash (In True IDE mode) INTERFACE
CF Chip Select 1
CF_nCS1
O8PU
This pin is the active low chip select 1 signal for the CF
ATA device
CF Chip Select 0
CF_nCS0
O8PU
This pin is the active low chip select 0 signal for the task
file registers of CF ATA device in the True IDE mode.
CF Register
Address 2
CF_SA2
O8
This pin is the register select address bit 2 for the CF
ATA device.
CF Register
Address 1
CF_SA1
O8
This pin is the register select address bit 1 for the CF
ATA device
CF Register
Address 0
CF_SA0
O8
This pin is the register select address bit 0 for the CF
ATA device.
CF Interrupt
CF_IRQ
IPD
This is the active high interrupt request signal from the
CF device.
CF
Data 15-8
CF_D[15:8]
I/O8PD
The bi-directional data signals CF_D15-CF_D8 in True
IDE mode data transfer.
In the True IDE Mode, all of task file register operation
occur on the CF_D[7:0], while the data transfer is on
CF_D[15:0].
The bi-directional data signal has an internal weak pull-
down resistor.
CF
Data7-0
CF_D[7:0]
I/O8PD
The bi-directional data signals CF_D7-CF_D0 in the
True IDE mode data transfer.
In the True IDE Mode, all of task file register operation
occur on the CF_D[7:0], while the data transfer is on
CF_D[15:0].
The bi-directional data signal has an internal weak pull-
down resistor.
IO Ready
CF_IORDY
IPU
This pin is active high input signal.
This pin has an internally controlled weak pull-up
resistor.
