Quad-Function Pin Assignment Registers
The quad function pin assignment registers allow each pin controlled by each register bit to be configured
for the primary, alternate 1 (secondary), alternate 2 (tertiary), and GPIO (quaternary) functions. The fields
are described in
, which applies to all quad-function registers.
