Hello, 1) May I know the best way to utilize the register banks for OS functions, ISR and Application functions? 2) What is the difference in terms of code speed and size if a) i were to use the default reg bank 0 and call another function which also uses the reg bank 0 (keil saves the registers automatically) b) i'm "using 3" in a function and calls another function also "using 3" ( i manually saves the registers ) Regards, KC
