NAME cpTRAPcc -- Exception generation on coprocessor condition
SYNOPSIS
cpTRAPcc 
cpTRAPcc#<data>
No size specs, or size of data: (Word, Long).
FUNCTION If specified coprocessor condition is true, exception vector no7 is generated. Value of saved PC is next instruction one (return address).
If given condition is false, PC takes the value of next instruction. Immediate data placed at instruction end is an information which can be used by the exception sub-routine.

OP-MODE
010->instruction contains a 16 bits operand.
011->instruction contains a 32 bits operand.
100->instruction has no operands.
CP-ID field identify coprocessor (1 to 7). If CP-ID=0, "line emulation F" exception is generated.
"COPROSSESSOR CONDITION" field, specifies condition to test. This condition is addressed to coprocessor which, after examining this one, address directives to processor in order to execute the instruction.
RESULT Not affected.
