NOTE
All register bits in this module are completely synchronous to internal
clocks during a register read.
NOTE
Figure of port data registers also display the alternative functions if
applicable on the related pin as defined in Table 2-1. Names in brackets
denote the availability of the function when using a specific routing option.
NOTE
Figures of module routing registers also display the module instance or
module channel associated with the related routing bit.
