As a result of this operation, bit 0 in PCR5 becomes 0, making P50 an input port. However, bits 7
and 6 in PCR5 change to 1, so that P57 and P56 change from input pins to output pins. To prevent
this problem, store a copy of the PCR5 data in a work area in memory and manipulate data of the
bit in the work area, then write this data to PCR5.
