A high density 68 pin SCSI III front panel connector and backplane IO provide system wiring options. Two IO channels can be used as interrupt generators. Interrupts are programmable to be based on level or edge and active high or low. An external clock and clock enable can be used or the internal clock selected for capturing the Input channels. The registers are mapped as 32 bit words and support byte, word and 32 bit access.
All registers are read-writeable.
Parallel Interface 64 independent channels. Each channel can be an input or an output. Pull-up Resistor 470 standard, 1K, 4.7K available Cable interface Industry standard SCSI III front panel IO and Pn4 backplane connection. Software Interface 2 - 32 bit registers mapped to the 64 IO channels. Byte, Word Long writeable.
