Pin Description -VS1 -VS2 (PC Card Memory Mode) -VS1 -VS2 (PC Card I/O Mode) -VS1 -VS2 (True IDE Mode) O 33 40 Voltage Sense Signals. -VS1 is grounded on the Card and sensed by the Host so that the CompactFlash Storage Card CIS can be read at 3.3 volts and -VS2 is reserved by PCMCIA for a secondary voltage and is not connected on the Card. This signal is the same for all modes. This signal is the same for all modes. -WAIT (PC Card Memory Mode – Except Ultra DMA Protocol Active) -WAIT (PC Card I/O Mode –Except Ultra DMA Protocol Active) IORDY (True IDE Mode – Except Ultra DMA Protocol Active) -DDMARDY (All Modes – Ultra DMA Write Protocol Active) DSTROBE (All Modes – Ultra DMA Read Protocol Active) O 42 The -WAIT signal is driven low by the CompactFlash Storage Card to signal the host to delay completion of a memory or I/O cycle that is in progress. This signal is the same as the PC Card Memory Mode signal. In True IDE Mode, except in Ultra DMA modes, this output signal may be used as IORDY. In all modes, when Ultra DMA mode DMA Write is active, this signal is asserted by the device during a data burst to indicate that the device is ready to receive Ultra DMA data out bursts. The device may negate -DDMARDY to pause an Ultra DMA transfer. In all modes, when Ultra DMA mode DMA Read is active, this signal is the data in strobe generated by the device. Both the rising and falling edge of DSTROBE cause data to be latched by the host. The device may stop generating DSTROBE edges to pause an Ultra DMA data in burst. -WE (PC Card Memory Mode) -WE (PC Card I/O Mode) -WE (True IDE Mode) I 36 This is a signal driven by the host and used for strobing memory write data to the registers of the CompactFlash Storage Card when the card is configured in the memory interface mode. It is also used for writing the configuration registers. In PC Card I/O Mode, this signal is used for writing the configuration registers. In True IDE Mode, this input signal is not used and should be connected to VCC by the host. WP (PC Card Memory Mode) Write Protect -IOIS16 (PC Card I/O Mode) -IOCS16 (True IDE Mode) O 24 Memory Mode – The CompactFlash Storage Card does not have a write protect switch. This signal is held low after the completion of the reset initialization sequence. I/O Operation – When the CompactFlash Storage Card is configured for I/O Operation Pin 24 is used for the -I/O Selected is 16 Bit Port (-IOIS16) function. A Low signal indicates that a 16 bit or odd byte only operation can be performed at the addressed port. In True IDE Mode this output signal is asserted low when this device is expecting a word data transfer cycle. |
