PORT C DATA REGISTER (PDRC)
The read/write 24-bit Port C Data Register (see Figure 10-21) is used to read or write data
to/from ESAI GPIO pins. Bits PD(11:0) 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 reflects 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
is reflected on this pin. If a port pin [i] is configured as disconnected, the corresponding PD[i]
bit is not reset and contains undefined data.
