Type
The host uses CS0# to select task file registers and CS1# to select alternate
Input
status registers and other device control register.
Device address signals used by the host to access device registers or data
Input
port.
The Device Active/Slave Present signal.
Input/Output
Note: the Mini PCIe form factor does not use this signal.
The I/O Read Enable signal is the strobe signal asserted by the host to read
Input
device registers or the data port.
The I/O Write Enable signal is the strobe signal asserted by the host to write
Input
device registers or the data port.
The host uses the DMA Acknowledge signal to acknowledge the receipt of the
Input
DMA Request and that it is ready to initiate DMA transfers.
The DMA Request signal is asserted by the drive when it is ready for data
Output transfer between it and the host. IORD and IOWR signals are used to control
the direction of data transfer.
Do Not Use. Must be left unconnected.
Input/Output 16-bit bidirectional I/O interface.
Supply Ground connection.
Output Device uses the Interrupt Request signal to interrupt the host.
The device asserts the I/O Ready signal to tell the host to extend the host
Output
transfer cycle.
Not connected.
The Pass Diagnostic signal is used by the master/slave handshake protocol to
determine if the device has passed diagnostics.
Input/Output
Note: the Mini PCIe form factor does not use this signal.
Reserved for Future Use.
Input The host asserts this signal to reset the device.
Supply Power supply.
