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. The third

mode of operation (MODE 2) is the bidirectional bus mode,

which uses 8 lines for a bidirectional bus and 5 lines, borrowing

one from the other group, for hand-shaking.
