	Table 8: Signal Descriptions (Continued)
	Signal Name	Pin	Type	Description
	VCC			This signal is the same for all modes.
	(PC Card I/O
	mode)
	VCC			This signal is the same for all modes.
	(True IDE mode)
	-VS1, -VS2	33, 40	O	Voltage Sense Signals.
				• -VS1 is grounded so that the
				SiliconDrive CF CIS can be read at
				3.3V.
				• -VS2 is reserved by PC Card for a
				secondary voltage.
	-VS1, -VS2			This signal is the same for all modes.
	(PC Card I/O
	mode)
	-VS1, -VS2			This signal is the same for all modes.
	(True IDE mode)
	-WAIT	42	O	The -WAIT signal is driven low by the
	(PC Card memory			SiliconDrive CF to signal the host to
	mode)			delay completion of a memory or I/O
				cycle that is in progress.
	-WAIT			This signal is the same as the PC
	(PC Card I/O			Card Memory Mode signal.
	mode)
	-IORDY			In true IDE mode, this output signal
	(True IDE mode)			may be used as IORDY.
	-WE	36	I	This is a signal driven by the host and
	(PC Card memory			used for strobing memory write data
	mode)			to the registers of the SiliconDrive CF
				when the card is configured in the

memory interface mode. This signal is also used for writing the configuration registers.

-WE

(PC Card I/O mode)

In PC Card I/O mode, this signal is used for writing the configuration registers.
