Explanation: To execute the BCLR instruction, the CPU begins by reading P4DDR. Since
P4DDR is a write-only register, it is read as H'FF, even though its true value is H'3F.
Next the CPU clears bit 0 of the read data, changing the value to H'FE.
Finally, the CPU writes this value (H'FE) back to P4DDR to complete the BCLR instruction.
As a result, P4

Example 2: BSET is executed to set bit 0 in the port 4 data register (P4DR) under the
following conditions.
