e
a register value is used to determine branching. The B register is
decremented, and if a non zero value remains, the value of the
displacement
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 result of decrementing leaves B with a zero value, the next instruction
executed is taken from the location following this instruction.
