JMPR
Syntax
Operation
Description
If the condition specified by op1 is met, program execution continues at the location of the instruction
pointer, IP, plus the specified displacement, op2. The displacement is a two's complement number which
is sign extended and counts the relative distance in words. The value of the IP used in the target address
calculation is the address of the instruction following the JMPR instruction. If the specified condition is not
met, program execution continues normally with the instruction following the JMPR instruction.
