Web17 jan. 2006 · That depends a bit on which PIC you're using. Generally, you write the address of the variable that you wish to access into the FSR-register and then access it through the INDF-register. PIC18-processors has more advanced methods for indirect access than PIC16-processors. For example, PIC18 contains three FSR-registers, has … WebMASM: Reverse the contents of an array in place. Use a loop with indirect or indexed addressing to reverse the elements of an integer array in place. Do. not copy the elements to any other array. Use the SIZEOF, TYPE, and LENGTHOF operators to make. the program as flexible as possible if the array size and type should be changed in the future.

To load a value from memory into a register using register-indirect addressing, we use a second register, known as the base register. This base register holds the actual memory address that the program is interested in. The LDR instruction inspects the base register ... WebThe indirect addressing mode in all its forms is used when you will not know the location of the data you want until the program is running. For example, in our 7-segment decoder example, we do not know ahead of time which number (0 to F) we want to decode. lpm Rd, Z Instruction Encoding Figure 6: Encoded Instructions Using Indirect Addressing duchar スペイン語

"Web5 jun. 2012 · The result is the "effective address," which is where the actual store (or load or other) operation will occur. This technique is referred to as postindexed indirect addressing and is a very common idiom in the 6502 universe. Postindexed indirection is the assembly language analog to using a pointer in C.

WebIndirect Indexed instructions are 2 bytes - the second byte is the zero-page address - $86 in the example. (So the fetched address has to be stored in the zero page.) While indexed indirect addressing will only generate a zero-page address, this mode's target address is not wrapped - it can be anywhere in the 16-bit address space.
