Instruction Set
LJMP addr16
Function:
Long jump
Description:
LJMP causes an unconditional branch to the indicated address, by loading the high-
order and low-order bytes of the PC (respectively) with the second and third
instruction bytes. The destination may therefore be anywhere in the full 64K
program memory address space. No flags are affected.
Example:
The label ”JMPADR” is assigned to the instruction at program memory location
1234H. The instruction
LJMP JMPADR
Operation:
at location 0123H will load the program counter with 1234H.
