This output line is always driven to a high state in Memory
Mode since a battery is not required for this product.
This output line is always driven to a high state in I/O Mode
since this product produces no audio.
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 card.
They are used by the host to determine that the card is fully
inserted into the socket.
This signal is the same as Memory Mode.
These signals are not used in IDE Mode.
These lines carry the data, commands, and host and the
controller. D00 is the LSB of the LSB of the Odd Byte of the
Word.
This signal is the same as the PC Card Memory Mode signal.
In True IDE Mode, all Task File operations occur in byte
mode on the low order bus D00-D07 while all data transfers
are 16 bit using D00-D15.
This signal is not used in this mode.
The I/O Write strobe pulse is used to clock I/O data onto the
data bus and into the controller registers. The clocking
occurs on the negative to positive edge of the signal (trailing
edge).
In True IDE Mode, this signal has the same function as in PC
Card I/O Mode.
This signal is not used in this mode.
This is an I/O Read strobe generated by the host. This signal
gates I/O data onto the bus from the CF Card.
In True IDE Mode, this signal has the same function as in PC
Card I/O Mode.
This is a signal driven by the host and used for strobing
memory write data into the registers. It is also used for writing
the configuration registers.
In PC Card I/O Mode, this signal is used for writing the
configuration registers.
In True IDE Mode, this input signal is not used and should be
connected to VCC.
This is an Output Enable strobe generated by the host interface.
It is used to read data from the CF Card in PC Card Memory
Mode and to read the CIS and configuration registers.
