Pin
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 READY 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 READY signal is held high
(disabled from being busy) when the CF Card is powered up
with RESET continuously disconnected or asserted high.
After card has been configured for I/O operation, signal is
used as active low interrupt request. Strobe low to generate
pulse mode interrupt or hold low for level mode interrupt.
In TrueIDE 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 TrueIDE 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 TrueIDE Mode, -CS0 is the chip enable 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.
