V1.1 8 -CD1, -CD2 (PC Card Memory Mode) -CD1, -CD2 (PC Card I/O Mode) -CD1, -CD2 (True IDE Mode) O 26,25 These Card Detect pins are connected to ground on the CompactFlash Storage Card. They are used by the host to determine that the CompactFlash Storage Card is fully inserted into its socket. This signal is the same for all modes. This signal is the same for all modes. Signal Name Dir. Pin Description -CE1, -CE2 (PC Card Memory Mode) Card Enable -CE1, -CE2 (PC Card I/O Mode) Card Enable -CS0, -CS1 (True IDE Mode) I 7,32 These input signals are used both to select the card and to indicate to the card whether a byte or a word operation is being performed. -CE2 always accesses the odd byte of the word.-CE1 accesses the even byte or the Odd byte of the word depending on A0 and -CE2. A multiplexing scheme based on A0,-CE1, -CE2 allows 8 bit hosts to access all data on D0-D7. See Table 27, Table 29, Table 31, Table 35, Table 36 and Table 37. This signal is the same as the PC Card Memory Mode signal. In the True IDE Mode, -CS0 is the address range select for the task file registers while -CS1 is used to select the Alternate Status Register and the Device Control Register. While –DMACK is asserted, -CS0 and –CS1 shall be held negated and the width of the transfers shall be 16 bits. -CSEL (PC Card Memory Mode) -CSEL (PC Card I/O Mode) -CSEL (True IDE Mode) I 39 This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This signal is not used for this mode, but should be connected by the host to PC Card A25 or grounded by the host. This internally pulled up signal is used to configure this device as a Master or a Slave when configured in the True IDE Mode. When this pin is grounded, this device is configured as a Master. When the pin is open, this device is configured as a Slave. |
