MA28155
1/20
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.
