DESCRIPTION
OCS[4:2]_N
IPU
Input from external current monitor indicating an over-
current condition. {Note: Contains internal pull-up to
3.3V supply}
GR[4:2]_N
I/O8
Green indicator LED for ports 2, 3 and 4. Will be active
low when LED support is enabled via EEPROM or
SMBus.
CompactFlash (In True IDE mode) INTERFACE
CF_nCS1
O8PU
This pin is the active low chip select 1 signal for the CF
ATA device
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_SA2
O8
This pin is the register select address bit 2 for the CF
ATA device.
CF_SA1
O8
This pin is the register select address bit 1 for the CF
ATA device
CF_SA0
O8
This pin is the register select address bit 0 for the CF
ATA device.
CF_IRQ
IPD
This is the active high interrupt request signal from the
CF device.
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_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.
CF_IORDY
IPU
This pin is active high input signal.
This pin has an internally controlled weak pull-up
resistor.
CF_nCD2
IPU
This card detection pin is connected to the ground on
the CF device, when the CF device is inserted.
This pin has an internally controlled weak pull-up
resistor.
CF_nCD1
IPU
This card detection pin is connected to ground on the
CF device, when the CF device is inserted.
This pin has an internally controlled weak pull-up
resistor.
CF_nRESET
O8
This pin is an active low hardware reset signal to CF
device.
