Prior to executing BSET
BSET instruction executed
After executing BSET
Description on operation
When the BSET instruction is executed, first the CPU reads port 5.
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.
Next, the CPU sets bit 0 of the read data to 1, changing the PDR5 data to H'41.
Finally, the CPU writes H'41 to PDR5, completing execution of BSET.
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.
