I/O These are the SCSI control signal input and output pins.
I/O These are the SCSI control signal input and output pins.
I/O These are the SCSI control signal input and output pins.
I/O These are used to input and output SCSI data bus signals.
I/O
I/O Upper byte and parity of data bus

They can be connected directly to a single-ended SCSI connector.
Either open-drain or totem pole output can be selected.
They can be connected directly to a single-ended SCSI connector.
The output buffer is the totem pole type.
They should be used as control signals for the external differential
driver/receiver circuit.

status.
They should be used as control signals for the external differential
driver/receiver circuit.
This is used to input signal for selecting the chip operation mode.
While 0 is input to this pin, all the SCSI control signals, data bus
output control signals, INIT, and TARG signals are fixed with L level.
This pin is used for a system clock input for SCSI protocol
controller block. (Max. 40 MHz)
This is used to input signals for the MPU to select the SPC as the
I/O device.
This is used to input select signals (external circuit select signals)
for the MPU to input and output the DMA data bus data via the
SPC.
When CS0 input valid: I/O ports for internal registers in SPC
When CS1 input valid: I/O ports for DMA bus data
When CS0 input valid: I/O ports for internal registers in SPC
When CS1 input valid: I/O ports for DMA bus data
Single-ended: Input 0
Differential-ended: Input 1
