However, the card may also be configured to operate in systems that support only the memory interface standard. The CompactFlash card configuration is controlled using the standard PCMCIA configuration registers starting at address 200h in the Attribute Memory space of the card. Table 3-4 describes the I/O signals. Signals whose source is the host are designated as inputs while signals that the card sources are outputs. SanDisk CompactFlash Memory Card logic levels conform to those specified in Section 3.3 of the PCMCIA Release 2.1 Specification. NOTE: The sleep-to-write and sleep-to-read times are the time it takes the card to exit sleep mode when any command is issued by the host to when the card is reading or writing. CompactFlash Memory cards do not require a reset to exit sleep mode. © 2007 SanDisk Corporation 3-3 Rev. 12.0, 02/07
