These address lines along with the -REG signal are used to select the following:
The I/O port address registers within the CompactFlash Storage Card , the
memory mapped port address registers within the CompactFlash Storage Card,
a byte in the card's information structure and its configuration control and status
registers.
This signal is the same as the PC Card Memory Mode signal.
In True IDE Mode, only A[02:00] are used to select the one of eight registers
in the Task File, the remaining address lines should be grounded by the host.
This signal is asserted high, as BVD1 is not supported.
This signal is asserted low to alert the host to changes in the READY and Write
Protect states, while the I/O interface is configured. Its use is controlled by the
Card Config and Status Register.
In the True IDE Mode, this input / output is the Pass Diagnostic signal in the
Master / Slave handshake protocol.
This signal is asserted high, as BVD2 is not supported.
This line is the Binary Audio output from the card. If the Card does not support
the Binary Audio function, this line should be held negated.
In the True IDE Mode, this input/output is the Disk Active/Slave Present signal in
the Master/Slave handshake protocol.
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.
