NAME
cpBcc -- Branch on coprocessor condition
SYNOPSIS
cpBcc <label>
Offset size = (Word, Long)
FUNCTION
If specified coprocessor condition is true, program execution
continues to address pointed by searching PC more offset.
Searching PC contains address of first word of offset. Offset is
a signed value of 16 or 32 bits, which represents the relative gap
in bytes between the searching PC and destination address.

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.
