|                make things easier just stuff the parameter RAM value into |
|                the ert registers. It does not matter if there are 1 or 2  |
|                edges.                                                     |
|              1. Get value from parameter RAM and store in ERTa and ERTb.  |
|              2. Then goto TCR tranistion routine.                         |
