program depending on the results of a test on the Carry Flag. If the flag is
equal to 0, the value of the displacement
(PC) and the next instruction is fetched from the location designated by the
new contents of the PC. The jump is measured from the address of the
instruction Op Code and has a range of -126 to +129 bytes. The assembler
automatically adjusts for the twice incremented PC.
If the flag is equal to a 1, the next instruction executed is taken from the
location following this instruction.
If the condition is met:
If the condition is not met:
The Carry Flag is reset and it is required to repeat the jump instruction. The
