on bytes, words, or long words, and most instructions can use any of the 14 addressing
modes.
Combining instruction types, data types, and addressing modes provides over 1000 useful
instructions. These instructions include signed and unsigned multiply and divide, quick arith-
metic operations, BCD arithmetic, and expanded operations (through traps).
