The PIC instruction set refers to the set of instructions that a 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
ADDWF instruction. ? ADDWF fileReg, d. ? Add the contents of WREG and a file register. ? Destination, d. If d="0", result is placed in WREG. If d="1", result is placed in file register. ? Ex1. MOVLW 28H. MOVWF 5H. MOVLW 56H. ADDWF 5H, 0 or ADDWF 5H, 1. (ADDWF 5H, W or ADDWF 5H, F). 13
9. Instruction Set. Similar to most microcontrollers, PIC supports only two arithmetic instructions- addition and subtraction. Flags C, DC, Z are The first line of the subroutine ( instruction ADDWF PCL,f )simply adds a literal "k" from W register and table start address which is stored in the PCL register. The result is real data
Slide Number. ControlHandler. Let's look at some arithmetic functions now, the first one being the Add W File instruction. This instruction allows you to add two 8 bit numbers together and produce an 8 bit result. Lets look at an example where we have defined a register called temp and we have put the value 0x53 hex into
Re:Addwf Instruction Wednesday, May 11, 2011 3:35 AM (permalink). 0. f is NOT a value, but the ADDRESS (actually the lowest 7 bits) of a RAM location holding the value. Your PIC architecture has RAM address space split into banks of 128 locations each #2. Danmods. New Member. Total Posts : 30
2 Mar 2011 Arithmetic and logic operation group instructions are used for performing all arithmetic operations and logic operations. By using these types of instructions, the PIC chip can easily perform all arithmetic and logic operations inside the micro controller (PIC). The arithmetic operations are addition (ADD),
Instruction, Description. ADDLW k, Add the content of W register with a literal value and store the result in the W register. ADDWF f , d, Add the content of W register with the content of a file register 'f'. If d is 0 the result is stored in the W register, if d is 1 the result is stored back to the file register 'f'. SUBLW k, Subtract the
