As a result of the BSET instruction, bit 0 in PDR5 becomes 1, and P50 outputs a high-level signal.
However, bits 7 and 6 of PDR5 end up with different values. To prevent this problem, store a copy
of the PDR5 data in a work area in memory. Perform the bit manipulation on the data in the work
area, then write this data to PDR5.

The PDR5 value (H'80) is written to a work area in
memory (RAM0) as well as to PDR5.
The BSET instruction is executed designating the PDR5
work area (RAM0).
The work area (RAM0) value is written to PDR5.
