mode, additional registers are provided for setting individual I/O signals (via the
GPxSET registers), for clearing individual I/O signals (via the GPxCLEAR registers), for toggling individual I/O
signals (via the GPxTOGGLE registers), or for reading/writing to the individual I/O signals (via the GPxDAT
registers). Table 61 lists the GPIO Data Registers.
