Input from external current monitor indicating an over-
current condition. {Note: Contains internal pull-up to
3.3V supply}
Green indicator LED for ports 2, 3 and 4. Will be active
low when LED support is enabled via EEPROM or
SMBus.
This pin is the active low chip select 1 signal for the CF
ATA device
This pin is the active low chip select 0 signal for the task
file registers of CF ATA device in the True IDE mode.
This pin is the register select address bit 2 for the CF
ATA device.
This pin is the register select address bit 1 for the CF
ATA device
This pin is the register select address bit 0 for the CF
ATA device.
This is the active high interrupt request signal from the
CF device.
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.
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.
This pin is active high input signal.
This pin has an internally controlled weak pull-up
resistor.
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.
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.
This pin is an active low hardware reset signal to CF
device.
