(1) The word "Reserved" means that there is no peripheral assigned to this GPxMUX1/2 register setting. Should it be selected, the state of
the pin will be undefined and the pin may be driven. This selection is a reserved configuration for future expansion.
(2) I = Input, O = Output, OD = Open Drain
(3) The eQEP2 peripheral is not available on the 80-pin PN or PFP package.
