/*
* NOTE: Pre-setting the auto-dec values for MMR1 to 0xF6F6 is a work-around for an "EKBEE1"
* diagnostic (PC 056710), which tests what happens when a misaligned read triggers a BUS trap,
* and that trap then triggers an MMU trap during the first pushWord() below.
*
* One would think it would be fine to zero those bits by setting lastOp to vector alone,
* and then letting each of the pushWord() calls below shift their own 0xF6 auto-dec value into
* lastOp. When the first pushWord() triggers an MMU trap, we obviously won't get to the second
* pushWord(), yet the diagnostic expects TWO auto-decs to be recorded. I'm puzzled why the
* hardware apparently indicates TWO auto-decs, if SP wasn't actually decremented twice, but who
* am I to judge.
