CC2340R5 to CC2340R22 Porting Guide

This section will describe, in general terms, how to migrate a project developed for the CC2340R5 device to a CC2340R22 device running the SimpleLink Low Power F3 SDK. However, it is important to first assess the differences between both devices to make sure that the project migration is possible.

The primary difference between CC2340R5 and CC2340R22 is the Flash size, as specified in their respective datasheets. CC2340R5 has 512kB Flash, and CC2340R22 has 256kB Flash.
