DATASHEET
xD_nRE
16
O12PU
xD Read Enable
This pin is an active low read strobe signal for the xD
device.
When using the internal FET, this pin has a weak
internal pull-up resistor that is tied to the output of the
internal power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used).
xD_nWE
12
O12PU
xD Write Enable
This pin is an active low write strobe signal for the xD
device.
When using the internal FET, this pin has a weak
internal pull-up resistor that is tied to the output of the
internal power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used).
xD_nB/R
17
IPU
xD Busy or Data Ready
This pin is connected to the BSY/RDY pin of the xD
device.
When using the internal FET, this pin has a weak
internal pull-up resistor that is tied to the output of the
internal power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used).
GPIO14
(xD_nCD)
19
I/O12
xD Card Detection GPIO
This is a GPIO designated by the default firmware as
the xD-Picture card detection pin.
xD_nCE
15
O12PU
xD Chip Enable
This pin is the active low chip enable signal to the xD
device.
When using the internal FET, this pin has a weak
internal pull-up resistor that is tied to the output of the
internal power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used).
