M8192 KDJ11-A ZKDJB2 XXDP Test Failure

[Jay Jaeger]

I have fiche for ZKDJB0, and fortunately it seems to match at this
particular error and address.

"This test looks for BEVENT to Interrupt when BIT 6 in the BEVENT
Control register is set and interrupt priority level is set to 5".

The particular error that you identify occurs as the result of an EMT
trap anywhere during the test.  However, the most likely error would be
that the BEVENT interrupt did not occur.  It would seem that the most
likely cause is that you have not configured the LTC clock interrupt -
but I am on my way out the door so I don't have time to look at the
KDJ11 manual to confirm this.

You can bypass this test by setting bit 10 of the XXDP switch register
to 1.  This is something you don in XXDP *before* you start the test
program (before you enter the "R" command).
