WebbThe instruction set of PIC16F84A has 35 instructions [The controller “understands” 35 words].These instructions are otherwise called Mnemonics. While introducing about the PIC16F84A till the hello world program, 7 instructions are introduced to you which were, BSF – bit set f. BCF- bit clear f. MOVLW – move literal value to W-register. Webb- Can be an assembly instruction mnemonic or assembly directive - Must begin in column two or greater - Must be separated from the label by a colon, one or more spaces or tabs addlw 0x10 ; addlw is the mnemonic field loop incf 0x30,W,A ; incf is a mnemonic false equ 0 ; equ is the mnemonic field
The PIC instruction set refers to the set of instructions that Microchip Technology PIC or dsPIC microcontroller supports. The instructions are usually programmed into the Flash memory of the processor, and automatically executed by the microcontroller on startup. PICmicro chips have a Harvard architecture and instruction words have unusual sizes. Originally, 12-bit instructions included 5 address bits to specify the memory operand, and 9-bit branch desti… Webb9 aug. 2011 · Generates a series of RETLW instructions, one instruction for each expr. Each expr must be an 8-bit value. Each character in a string is stored in its own RETLW instruction. 4.19.3 Usage This directive is used in the following types of code: absolute or relocatable. For information on types of code, see Section 1.6 “Assembler Operation”.
