Function
Test pins. These pins must be connected to VSS0.
LSI reset. The LSI is reset on a 0 input.
Selects active-high or active-low for the microcontroller CS logic.
Selection pin that must be set to 1 when XTALCK1 is used.
SCSI block oscillator circuit input. Selected by X1EN.
SCSI block oscillator circuit output.
WAIT signal output to the microcontroller
Microcontroller data signals
Microcontroller data read signal input
Microcontroller data write signal input
Input for the register chip select signal from the microcontroller
Register chip select signal from the microcontoller
Interrupt request output to the microcontroller (ECC side. Set with a register.)
Interrupt request output to the microcontroller (SCSI side. Set with a register.)

SCSI connection
Note: 1. NC pins must be left open. Do not connect any signal to these pins.
2. Pin names that start with Z are negative-logic signals.
3. VSS0 is the logic system ground and VSS1 is the SCSI interface ground.
4. Applications that use DRAM must insert resistors in the CAS and RAS lines, connect capacitors between these lines and ground, and take any
other measures necessary to prevent undershoot in the DRAM related circuits.
5. Since these circuits include buffers that sink 48 mA, adequate noise prevention measures must be applied.
