exception priority for BCM1250

["Lijun Chen" <chenli@nortelnetworks.com>]

Hi,

Does anybody know which mips family SB1 core on bcm1250 falls into?
It is a MIPS64 processor, does it belong to 5K family or 20Kc?

What about the exception priorities, such as cache error exception, bus 
error
exception, and so on? Are they maskable or non-maskable? It is not clear 
from
BCM1250 and sb1 core manuals.

Thanks a lot.
