Section 2 CPU
1. When the BSET instruction is executed, first the CPU reads port 5.
2. Next, the CPU sets bit 0 of the read data to 1, changing the PDR5 data to H'41.
3. Finally, the CPU writes H'41 to PDR5, completing execution of BSET instruction.
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.

After executing BSET instruction
Description on operation
Since P57 and P56 are input pins, the CPU reads the pin states (low-level and high-level
input).
P55 to P50 are output pins, so the CPU reads the value in PDR5. In this example PDR5 has a
value of H'80, but the value read by the CPU is H'40.
