Branch Instruction Execution Times
<EA>
<ea>
<ea>
The execution times for moving the contents of the Racc, Raccext[01,23],
MACSR, or Rmask into a destination location <ea>x shown in this table
represent the best-case scenario when the store instruction is executed and
there are no load or M{S}AC instructions in the EMAC execution pipeline.
In general, these store operations require only a single cycle for execution,
but if preceded immediately by a load, MAC, or MSAC instruction, the
depth of the EMAC pipeline is exposed and the execution time is four
cycles.
