For lowest power dissipation, leave these signals open.2. Should be grounded by the host.3. Should be tied to VCC by the host.4. Refer to Section 3.3 for definitions of In, Out type.5. CompactFlash products support multiword DMA in anticipation of the CF SpecificationRev. 2.1 release.3.2 Electrical DescriptionThe TRS* CompactFlash Cards are optimized for operation with hosts that support the PCMCIA I/Ointerface standard conforming to the PC Card ATA specification. However, the CompactFlash Cardsmay also be configured to operate in systems that support only the memory interface standard. Theconfiguration of the CompactFlash Cards are controlled using the standard PCMCIA configurationregisters starting at address 200h in the Attribute Memory space of the CompactFlash Memory Card.Table 3.2 describes the I/O signals. Signals are designated as inputs when their source is the host,while signals that the CompactFlash Memory Card sources are outputs. The CompactFlash Card logiclevels conform to those specified in the PCMCIA Release 2.1 Specification. See Section 3.3 fordefinitions of Input and Output type.Table 3.2 Signal DescriptionSignal Name Dir. DescriptionA10—A0(PC Card Memory Mode)A10—A0(PC Card I/O Mode)A2—A0(True IDE Mode)A10—A3(True IDE Mode)BVD1(PC Card Memory Mode)-STSCHG(PC Card I/O Mode)Status Changed-PDIAG(True IDE Mode)II/OThese address lines along with the -REG signal are used to select the following: TheI/O port address registers within the CompactFlash Card, the memory mapped portaddress registers within the card, a byte in the card's information structure and itsconfiguration control and status registers.This signal is the same as the PC Card Memory Mode signal.In True IDE Mode only A[2:0] is used to select the one of eight registers in the TaskFile.In True IDE Mode these remaining address lines should be grounded by the host.This signal is asserted high as the BVD1 signal since a battery is not used with thisproduct.This signal is asserted low to alert the host to changes in the RDY/-BSY and WriteProtect states, while the I/O interface is configured. Its use is controlled by the CardConfig and Status Register.In the True IDE Mode, this input/output is the Pass Diagnostic signal in theMaster/Slave handshake protocol.TRS* Tele-Radio-Space GmbH, reserves the right Page 17 from 113 Industrial-Grade CompactFlash Cardto change products or specifications without notice.
