ceprocessor instruction operation word. This primitive applies to general
category instructions. If the coprocessor issues this primitive during the ex-
ecution of a conditional category instruction, the main processor initiates

This primitive uses the CA, PC, and DR bits as previously described.
The valid effective address field (bits [8-10]) of the primitive format specifies
the valid effective address categories for this primitive. If the effective address
specified in the instruction operation word is not a member of the class
specified by bits E8-10], the main processor aborts the coprocessor instruc-
tion by writing an abort mask (refer to 10.3.2 Control CIR) to the control CIR
