PORT D DATA REGISTER (PDRD)
The read/write 24-bit Port D Data Register is used to read or write data to/from the DAX
GPIO pins. Bits PD[1:0] are used to read or write data from/to the corresponding port pins if
they are configured as GPIO. If a port pin [i] is configured as a GPIO input, then the
corresponding PD[i] bit will reflect the value present on this pin. If a port pin [i] is configured
as a GPIO output, then the value written into the corresponding PD[i] bit will be reflected on
the this pin. Hardware and software reset clear all PDRD bits.
