The I/O controller configures I/O pins and maps peripheral signals to physical pins (DIOx) on the CC13x4x10 and CC26x4x10 device packages. This chapter explains the I/O controller function and gives a few examples on how to map peripheral functions to the pins chosen by the user.
Several similar terms are defined as follows:
PORT_ID is the number for a peripheral function.
GPIO is a peripheral function with a PORT_ID of 0x0.
DIOn (DIO0 to DIO47) are the logical names of the different I/O pins on the specific package.
Eight of these DIOs also have analog capabilities. The device-specific data sheet provides the mapping between DIO and pins for the different packages.
