Enhanced Multiply-Accumulate Unit (EMAC)
if extension word, bit [5] = 1, the MASK bit, then
Here, oa is the calculated operand address and se_d16 is a sign-extended 16-bit displacement. For
auto-addressing modes of post-increment and pre-decrement, the calculation of the updated An
value is also shown.
Use of the post-increment addressing mode, {(An)+} with the MASK is suggested for circular
queue implementations.
