CS0# is used to select the Command Block
Registers. CS1# is used to select the Control Block
Registers.
DIOR# is used to read data from the Drive’s I/O space.
DIOW# is used to write data to the Drive’s I/O space.
This signal shall be used by the host in response to
DMARQ to either acknowledge that data has been
accepted, or that data is available.
This signal, used for DMA data transfer between host
and drive, shall be asserted by the drive when it is
ready to transfer data to or from the host.
This signal is active high interrupt request to the host.
This output signal is asserted when the I/O port
address is capable of 16-bit access.
This signal is the DISK Active/Slave Present signal in
the Master/Slave handshake protocol.
This input pin is the active low hardware reset from the
host.
This signal is asserted to delay completion of the
memory or I/O access cycle.
This signal is the Pass Diagnostic signal in the
Master/Slave handshake protocol.
This signal is used to configure this Drive as a Master
or a Slave. When this signal is grounded, this Drive is
configured as a Master. When this signal is Open, this
Drive is configure as a Slave.
