GPIO mux
The GPIO Mux registers, are used to select the operation of shared pins on the F2810 and F2812 devices. The
pins can be individually selected to operate as
Digital I/O
or connected to
Peripheral I/O
signals (via the
GPxMUX registers). If selected for
Digital I/O
mode, registers are provided to configure the pin direction (via
the GPxDIR registers) and to qualify the input signal to remove unwanted noise (via the GPxQUAL) registers).
Table 60 lists the GPIO Mux Registers.

Registers that are not implemented will return undefined values and writes will be ignored.
Not all inputs will support input signal qualification.
§
These registers are EALLOW protected. This prevents spurious writes from overwriting the contents and corrupting the system.
