Name and Functions
A[2:0] are used to select one of eight registers in the Task File.
D[15:0] Data bus
DMA Acknowledge - input from host
DMA Request to host
CS1FX# is the chip select for the task file registers
Device Control register.
This internally pulled-up signal is used to configure this device
as a Master or a Slave. When this pin is grounded, this device
is configured as a Master. When the pin is open, this device is
configured as a Slave. The pin setting should remain the same
from Power-on to Power-down.
This is an I/O Read strobe generated by the host. This signal
gates I/O data onto the bus from the chip.
The I/O Write strobe pulse is used to clock I/O data into the
chip.
This output signal is asserted low when the device is indicating
a word data transfer cycle.
This signal is the active high Interrupt Request to the host.
The Pass Diagnostic signal in the Master/Slave handshake
protocol.
The Drive Active/Slave Present signal in the Master/Slave
handshake protocol.
This input pin is the active low hardware reset from the host.
CS3FX# is used to select the alternate status register and the
