Note
Although the SPBL and RPBL instructions are to set or reset a specified bit, they also output port contents (in 4-bit units) including the specified bit
as soon as the specified bit has been set or reset (the contents of the output latch are output to pins other than the specified bit). Before executing
these instructions, initialize the contents of the output latch by executing the OPL instruction.
