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 or CF+Card, the memory mapped port address
registers within the CompactFlash Storage Card or CF+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[2:0] 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
RDY/-BSY and Write Protect states, while the I/O interface is
configured.
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 or CF+Card.
host to determine that the CompactFlash Storage Card or CF+Card is
fully inserted into its socket.
This signal is the same for all modes.
This signal is the same for all modes.
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, -CE1accesses 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 Tables 4-11, 4-12, 4-15, 4-16 and
4-17.
This signal is the same as the PC Card Memory Mode signal.
In the True IDE Mode CS0 is the chip select for the task file registers
while CS2 is used to select the Alternate Status Register and the
Device Control Register.
Its use is controlled by the Card Config and Status
