Coprocessor ID field—Identifies the coprocessor for this operation; coprocessor ID of
condition is true, the processor initiates a cpTRAPcc exception, vector number 7. The
program counter value placed on the stack is the address of the next instruction. If the
selected condition is not true, no operation is performed, and execution continues with
the next instruction. The coprocessor determines the specific condition from the
condition word that follows the operation word. Following the condition word is a user-
defined data operand specified as immediate data to be used by the trap handler.
Opmode field—Selects the instruction form.
Coprocessor Condition field—Specifies the coprocessor condition to be tested. This
010— Instruction is followed by one operand word.
011— Instruction is followed by two operand words.
100— Instruction has no following operand words.
