PD4_2 set to 0. When read, the content is 0.
PD5_0 to PD5_2, and PD5_5, set to 0. When read, the content is 0. Also, bits PD5_3 and PD5_4 are reserved
bits. If it is necessary to set bits PD5_3 and PD5_4, set to 0. When read, the content is undefined.
The PDi register selects whether I/O ports are used for input or output. Each bit in the PDi register corresponds
to one port.
