MA28155 MA28155 Radiation Hard Programmable Peripheral Interface Replaces June 1999 version, DS3575-4.0 DS3575-5.0 January 2000 The MA28155 is a general purpose programmable Input/ Output device designed for use with the MAS281 microprocessor. It has 24 I/O pins which may be individually programmed in 2 groups of 12 and used in 3 major modes of operation. In the first mode (MODE 0), each group of 12 I/O pins may be programmed in sets of 4 to be inputs or outputs. In the second mode (MODE 1), each group may be programmed to have 8 lines of input or output. Of the remaining 4 pins, 3 are used for hand-shaking and interrupt control signals.
