I/O Control
This chapter describes the input/output controller (IOC) and the general-purpose inputs/outputs (GPIOs).
The IOC design provides a flexible configuration, as most of the peripheral ports can be mapped to any of
the physical I/O pads (I/O at die boundary). The CC26xx chameleon series has up to 31 I/O pins
configurable as GPIO or to a peripheral function.
