	mode)

-IORD

(PC Card I/O mode)

This is an I/O read strobe generated by the host. This signal gates I/O data onto the bus from the SiliconDrive CF when the card is configured to use the I/O interface.

-IORD			In true IDE mode, this signal has the
(True IDE mode)			same function as the PC Card I/O
			mode.
-IOWR	35	I	This signal is not used in this mode.
(PC Card memory
mode)
-IOWR			The I/O write strobe pulse is used to
(PC Card I/O			clock I/O data on the Card data bus
mode)			into the SiliconDrive CF controller
			registers when the SiliconDrive CF is
			configured to use the I/O interface.
			The clocking occurs on the negative-
			to-positive edge of the signal (the
			trailing edge).
-IOWR			In true IDE mode, this signal has the
(True IDE mode)			same function as the PC Card I/O
			mode.
-OE	9	I	This is an output enable strobe
(PC Card memory			generated by the host interface, which
mode)			is used to read:
			• Data from the SiliconDrive CF in
			memory mode.
			• The CIS and configuration
			registers.
-OE			In PC Card I/O mode, this signal is
(PC Card I/O			used to read the CIS and
mode)			configuration registers.
