Restrictions: A JScc instruction used within a DO loop cannot specify the loop
address (LA) as its target.
A JScc instruction used within in a DO loop cannot begin at the address LA within that
DO loop.
A JScc instruction cannot be repeated using the REP instruction.
Example:
Explanation of Example: In this example, program execution is transferred to the sub-
routine at address P:(R3+N3) in program memory if the limit bit is set (L=1). Both the
return address (PC) and the status register (SR) are pushed onto the system stack prior
to transferring program control to the subroutine if the specified condition is true. If the
specified condition is not true, no jump is taken and the program counter is incremented
by 1.
Condition Codes:
The condition codes are not affected by this instruction.
