This primitive uses the PC bit as previously described. Bits [0-7] contain the
exception vector number used by the main processor to initiate exception
When the main processor receives this primitive, it acknowledges the co-
fer to 10.3.2 Control CIR) to the control CIR. The MC68030 then performs
exception processing as described in 8.1 EXCEPTION PROCESSING SE-
QUENCE. The vector number for the exception is taken from bits [0-7] of the
of the coprocessor instruction during which the primitive is received.
The take post-instruction exception primitive initiates exception processing
using a coprocessor-supplied exception vector number and the post-instruc-
ditional category instructions. Figure 10-44 shows the format of the take post-
instruction exception primitive.
