7 / 48 page  THNCFxxxMBA/BAI Series 2002-10-20 7/48 Preliminary Signal Name Dir Pin No. Description GND (PC Card Memory Mode) GND (PC Card I/O Mode) GND (True IDE Mode) 1,50 Ground −INPACK (PC Card Memory Mode) This signal is not used in this mode. −INPACK (PC Card I/O Mode) The Input Acknowledge signal is asserted by the CompactFlash Storage Card when the card is selected and responding to an I/O read cycle at the address that is on the address bus. This signal is used by the host to control the enable of any input data buffers between the CompactFlash Storage Card and the CPU. −INPACK (True IDE Mode) O 43 In True IDE Mode this output signal is not used and should not be connected at the host. −IORD (PC Card Memory Mode) This signal is not used in this 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 CompcatFlash Storage Card when the card is configured to use the I/O interface. −IORD (True IDE Mode) I 34 In True IDE Mode, this signal has same function as in PC Card I/O Mode. −IOWR (PC Card Memory Mode) This signal is not used in this mode. −IOWR (PC Card I/O Mode) The I/O Write strobe pulse is used to clock I/O data on the Card Data bus into the CompactFlash Storage Card controller registers when the CompactFlash Storage Card is configured to use the I/O interface. The clocking will occur on the negative to positive edge of the signal (trailing edge) −IOWR (True IDE Mode) I 35 In True IDE Mode, this signal has the same function as in PC Card I/O Mode. −OE (PC Card Memory Mode) This is an Output Enable strobe generated by the host interface .It is used to read data from the CompactFlash Storage Card in Memory Mode and to read the CIS and configuration registers. −OE (PC Card I/O Mode) In PC Card I/O Mode, this signal is used to read the CIS and configuration registers. −ATA SEL (True IDE Mode) I 9 To enable True IDE Mode this input should be grounded by the host. |
