NCR53C94 Overview
The 53C94, 53C95 and 53C96 are high performance CMOS devices conforming to the ANSI standard, X3.l3I-I986, for Small puter Systems Interface (SCSI). They are a super-set of the 53C90 with additional mands, registers and an I8-bit DMA interface (two parity bits). The microprocessor bus width is 8-bits, and may be configured to be separate from the I8-bit DMA bus (called dual bus) or share the lower half (called...
