Description
~National D Semiconductor JULY 1978 INS8254 N-Channel Bit Programmable Per~pherallnterface General .
Features
* The INSS254 is an LSI device which provides two S-bit ports of peripheral interfacing capability for microcomputer systems. The I/O chip contains two peripheral ports of eight bits each. Each of the I/O pins in the two ports may be defined as an input or an output to provide maximum flexibility. EaApplications
* a single bit of I/O in either port may be set, cleared or read with a single microproCessor instruction. In addition to basic I/O, one of the ports, port A, may be programmed to operate in several types of strobed mode with handshake. Strobed mode together with optional interrupt operation permit bINS8254 Distributors
