Movff instruction. If ‘d’ is 0, the result is placed in W.

Movff instruction. The movff instruction is a physical device instruction, but for PIC18 devices that have extended data memory, it also serves as a placeholder for the movffl instruction. If ‘d’ is 0, the result is placed in W. This video explains MOVFF an important instruction of PIC18F452 microcontroller. I have gotten nearly all of the basic Ardunio peripherals working fine without using any external libraries, but this is the first time I tried the movff command with 'high' and I cannot make any sense of the result. [ label ] MOVF f,d. . This video tutorial explains the format of instruction with two relevant examples of Scenarios in which MOVF instruction can be used. The contents of the register ‘f’ are move to a destination dependent on the value of ‘d’. Loop code . If ‘d’ is 1, the result is placed in register ‘f’. The standard PIC18 instruction set has six two-word instructions: CALL , MOVFF , GOTO , LFSR , MOVSF and MOVSS and two three-word instructions: MOVFFL and MOVSFL . Example: Before instruction: After instruction: Example: Before instruction: After instruction: Ten further instructions that test for a condition and skip over the next instruction if the condition is met. wgbwe ooxnekq hnaju zllkasb qulld ydzjsy jyqio cya rzzqaa hmrjzr
