Uno32 a) What instruction set is the PIC32 based on? b) How many general purpose registers does the PIC32 have? What is the word size? c) What is the purpose of the stack in calling a function? d) How would you set RE0, RE3, and RE6 to outputs and sets them to a digital high? (We are looking for the masks and registers used) e) How would you toggle these same bits with one command? f) List what the t, s, v, and a registers are used for
