Port C Data register (PDRC)

The read/write 24-bit Port C Data Register (see
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, the
corresponding PD[i] bit reflects the value present on this pin. If a port pin [i] is configured as a GPIO output, 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.

Port E (ESAI_1) GPIO - Pins and Registers

The GPIO functionality of the ESAI_1 port is controlled by three registers: Port E Control register (PCRE), Port E Direction register (PRRE)
and Port E Data register (PDRE).
