6.3 Analog Peripheral Connectivity
Many analog resources are routable and can be connected to numerous GPIO's. The table below indicates which peripherals are avali-
able on each GPIO port. When a differential connection is being used Positive inputs are restricted to the EVEN pins and Negative
inputs are restricted to the ODD pins. When a single ended connection is being used positive input is avaliable on all pins. See the
device Reference Manual for more details on the ABUS and analog peripherals.
