The default loading mode is automatically load when you create and edit a component in Nextion Assembly language programming is a method of writing programs using instructions that are the symbolic equivalent of machine code. The syntax of each instruction is structured to allow direct translation to machine code. This chapter begins the formal study of Microchip PIC18 assembly language programming. The extended instruction set is a feature of the PIC18 and higher series of chips which enable the compiler to generate more efficient code. Running in the extended instruction mode the Microchip compiler becomes even more difficult and picky to use so I have not noticed its loss.

XINST = OFF, 0xBF, Instruction set extension and Indexed Addressing mode. A 32 Mhz oscillator will result in an 8 Mhz instruction clock (Fosc/4) after the With the OSCTUNE set to 00h, the internal oscillator frequency will not be affected.
