In PC Card I/O Mode, this signal is used to read the CIS and
configuration registers.
To enable True IDE Mode, this input should be grounded by
the host.
In Memory Mode, this signal is set high when the CF Card is
ready to accept a new data transfer operation and held low
when the CF Card is busy. The host must provide a pull-up
resistor. At power up and at reset, the RDY/-BSY signal is
held low (busy) until the CF Card completes its power up or
reset function. No access of any type should be made to the
CF Card during this time. The
RDY/-BSY signal is held high (disabled from being busy)
when the CF Card is powered up with RESET continuously
disconnected or asserted high.
After the CF Card has been configured for I/O operation, this
signal is used as the active low interrupt request. This line is
strobed low to generate a pulse mode interrupt or held low
for a level mode interrupt.
In True IDE Mode, this signal is the active high interrupt
request to the host.
These address lines along with the -REG signal are used to
select the following: the I/O port address registers within the
CF Card, the memory mapped port address registers within
the CF Card, a byte in the CIS and the Configuration Control
and Status Registers.
This signal is the same as the PC Card Memory Mode signal.
In True IDE Mode only, A2:A0 are used to select the one of
eight registers in the Task File. The remaining address lines
should be grounded.
These input signals are used both to select the CF Card and
to indicate to the CF 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.
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 -CS1 is used to select the Alternate Status
Register and the CF Card Control Register.
This signal is not used for this mode.
This signal is not used for this mode.
This internally pulled up signal is used to configure the card
as a Master or Slave. When the pin is grounded, the card is
configured as a Master. When the pin is open, the card is
configured as a Slave.
This signal distinguishes between accesses to Common
Memory (high) and Register Attribute Memory (low).
