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.
