Figure 27-4 shows the signal connections of GPIO1.
Figure 27-4 GPIO1 Signal ConnectionsFigure 27-5 shows the signal connections of GPIO2 through GPIO8.
Figure 27-5 GPIO2 Through GPIO8 Signal ConnectionsFor more information about the GPIO1 through GPIO8 signals and channel description, see Section 27.4.7, General-Purpose Interface Channels Description.
For more information about GPIO signal multiplexing, see Pad Configuration Registers, and in Control Module.
GPIO pins can directly snoop device pads even if those are configured in the other modes. For GPIO output user needs to set pad mux.
