I am writing an assembly program (very basic bootloader) and wondering if there is a CPU-header file to use for assembly programs. For example, I would like to MOV the address of PORTA_PCR3 into R1. Sure, I can come up with my own header that includes everything I need but I don't want to do that if something is already provided.
Would .extern somehow work for these things?
I am using CW MCU 10.6 with a K60 CPU.
