Target
The Target options specify target-specific features for the IAR C/C++ Compiler and Assembler.
Use Core or Device
Select how you want to specify which target architecture you are developing for: Core, Device, or Custom Device.
Processor variant
Selects the target architecture:
- Core
The processor core you are using. For a description of the available variants, see ‑‑cpu.
