Signal Symbols and Descriptions
Symbol
Type
Description
CS0#, CS1#
Input
The host uses CS0# to select task file registers and CS1# to select alternate
status registers and other device control register.
DA[0...2]
Input
Device address signals used by the host to access device registers or data
port.
DASP#
Input/Output
The Device Active/Slave Present signal.
Note: the Mini PCIe form factor does not use this signal.
DIOR#
Input
The I/O Read Enable signal is the strobe signal asserted by the host to read
device registers or the data port.
DIOW#
Input
The I/O Write Enable signal is the strobe signal asserted by the host to write
device registers or the data port.
DMACK#
Input
The host uses the DMA Acknowledge signal to acknowledge the receipt of the
DMA Request and that it is ready to initiate DMA transfers.
DMARQ
Output
The DMA Request signal is asserted by the drive when it is ready for data
transfer between it and the host. IORD and IOWR signals are used to control
the direction of data transfer.
DNU
Do Not Use. Must be left unconnected.
DQ[0...15]
Input/Output
16-bit bidirectional I/O interface.
GND
Supply
Ground connection.
INTRQ
Output
Device uses the Interrupt Request signal to interrupt the host.
IORDY
Output
The device asserts the I/O Ready signal to tell the host to extend the host
transfer cycle.
NC
Not connected.
PDIAG#
Input/Output
The Pass Diagnostic signal is used by the master/slave handshake protocol to
determine if the device has passed diagnostics.
Note: the Mini PCIe form factor does not use this signal.
Reserved
Reserved for Future Use.
RESET#
Input
The host asserts this signal to reset the device.
VCC
Supply
Power supply.
