This input/output is the Disk Active/Slave Present signal in the Master/
Slave handshake protocol.
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.
The I/O Write strobe pulse is used to clock I/O data on the drive Data
bus into the Drive controller registers when the Drive is configured to
use the I/O interface. The clocking will occur on the negative to
positive edge of the signal (trailing edge).
This is an I/O Read strobe generated by the host. This signal gates I/O
data onto the bus from the Drive.
Signal is the active high Interrupt Request to the host.
A[2:0] are used to select the one of eight registers in the Task File.
-CS1 is the chip select for the task file registers while -CS2 is used to select
the Alternate Status Register and the Device Control Register.
This internally pulled up signal is used to configure this device as a Master
or a Slave. When the pin is grounded, this device is configured as a Master.
When the pin is open, this device is configured as a Slave
Not used.
This input/output is the Pass Diagnostic signal in the Master/Slave
handshake protocol.
Not used.
Not used.
Not used, and pulled up to VCC through a 4.7K ohm resistor.
This input pin is the active low hardware reset from the host.
Power. Applies to the 44-pin version only.
Ground. (Pin 43 applies to 44-pin version only.)
No connect
