Example: To clear only bit 4 in the port 1 P1DDR
The P1DDR register consists of 8 write-only bits and sets the I/O direction of the port 1 pins.
Reading this register is invalid. When read, the values returned are undefined.
Here we present an example in which P14 is specified to be an input port using the BCLR
instruction. First, we write the initial value H'F0 written to P1DDR to the work area in RAM
(RAM0).
