Example 2: BSET instruction executed designating port 3

signal at P3
example, the BSET instruction is used to change pin P3
[A: Prior to executing BSET]
[B: BSET instruction executed]
[C: After executing BSET]
[D: Explanation of how BSET operates]
When the BSET instruction is executed, first the CPU reads port 3.
Since P3
P3
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 PDR3 data to H'41. Finally, the CPU
writes this value (H'41) to PDR3, completing execution of BSET.
