Section 2 CPU
Example 2: The BSET instruction is executed for port 5.
P57 and P56 are input pins, with a low-level signal input at P57 and a high-level signal input at
P56. P55 to P50 are output pins and output low-level signals. An example to output a high-level
signal at P50 with a BSET instruction is shown below.

[Description on operation]
1. When the BSET instruction is executed, first the CPU reads port 5. Since P57 and P56 are
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.

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.
