TS1G~32GCF133				133X CompactFlash Card
	Signal Name	Dir.	Pin	Description
-IOWR		I	35	This signal is not used in this mode.
(PC Card Memory Mode)
-IOWR				The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the
(PC Card I/O Mode)				CompactFlash Storage Card controller registers when the CompactFlash
				Storage Card is configured to use the I/O interface.
				The clocking shall occur on the negative to positive edge of the signal (trailing
				edge).
-IOWR				In True IDE Mode, while Ultra DMA mode protocol is not active, this signal has
(True IDE Mode – Except				the same function as in PC Card I/O Mode. When Ultra DMA mode protocol is
Ultra DMA Protocol Active)				supported, this signal must be negated before entering Ultra DMA mode
				protocol.
STOP				In True IDE Mode, while Ultra DMA mode protocol is active, the assertion of this
(True IDE Mode – Ultra DMA				signal causes the termination of the Ultra DMA burst.
Protocol Active)
-OE		I	9	This is an Output Enable strobe generated by the host interface. It is used to read
(PC Card Memory Mode)				data from the CompactFlash Storage Card in Memory Mode and to read the CIS
				and configuration registers.
-OE				In PC Card I/O Mode, this signal is used to read the CIS and configuration
(PC Card I/O Mode)				registers.
-ATA SEL				To enable True IDE Mode this input should be grounded by the host.
(True IDE Mode)
READY		O	37	In Memory Mode, this signal is set high when the CompactFlash Storage Card is
(PC Card Memory Mode)				ready to accept a new data transfer operation and is held low when the card is
				busy.
				At power up and at Reset, the READY signal is held low (busy) until the
				CompactFlash Storage Card has completed its power up or reset function. No
				access of any type should be made to the CompactFlash Storage Card during
				this time.
				Note, however, that when a card is powered up and used with RESET
				continuously disconnected or asserted, the Reset function of the RESET pin is
				disabled. Consequently, the continuous assertion of RESET from the application
				of power shall not cause the READY signal to remain continuously in the busy
				state.
-IREQ				I/O Operation – After the CompactFlash Storage Card Card has been configured
(PC Card I/O Mode)				for I/O operation, this signal is used as -Interrupt Request. This line is strobed
				low to generate a pulse mode interrupt or held low for a level mode interrupt.
INTRQ				In True IDE Mode signal is the active high Interrupt Request to the host.
(True IDE Mode)
