4 Signal properties and muxing
Table 2 shows the signals properties for each pin on the PXR40. For each port pin that has an associated SIU_PCRn register to
control its pin properties, the supported functions column lists the functions associated with the programming of the
SIU_PCRn[PA] bit in the order: Primary function (P), Function 2 (F2), Function 3 (F3), and GPIO (G). See Figure 7.
Primary Functions
are listed First
Secondary Functions
are alternate functions
