As a result of this operation, bit 0 in PDR3 becomes 1, and P3
However, bits 7 and 6 of PDR3 end up with different values.
To avoid this problem, store a copy of the PDR3 data in a work area in memory. Perform the bit
manipulation on the data in the work area, then write this data to PDR3.

The PDR3 value (H'80) is written to a work area in memory
(RAM0) as well as to PDR3.
The BSET instruction is executed designating the PDR3
work area (RAM0).
The work area (RAM0) value is written to PDR3.
