Section 2 CPU
To switch P14 from being an output pin to being an input pin, we must change the value of
P1DDR bit 4 from 1 to 0 (H'F0 → H'E0). Here, were execute a BCLR instruction for RAM0.
BCLR
Since RAM0 can be read and written, when the bit manipulation instruction is executed, only bit 4
in RAM0 is cleared. Then we write this RAM0 value to P1DDR.
MOV.B
MOV.B
If this procedure is used to write registers that include write-only bits, programs can be written
without depending on the type of the instructions used.
