Major refactor. Major improvements. All ISR/IRQ stuff moved into its own header and source. Comments added on all major parts. Some optimisations in important functions. All ASM removed for ISR and IRQ, instead using new GCC directives. 2019-06-27 18:57:54 +00:00			`CC:=$(PREFIX)/bin/$(DEFAULT_HOST)-gcc`
