Excuse me, I have the registers reversed. I see that the 60x Bus
Transfer Error Status and Control Register 1 (TESCR1) is 0x80020000
and that the 60x Bus Transfer Error Status and
Control Register 2 (TESCR2) is 0x000 0000. This tells me that there
was a 60x bus monitor time-out and that the Transfer Type is 0010b.
