LDA stands for LoaD Accumulator. LDA is one of six memory operations in the 6502 instruction set. The LDA operator is used to load a byte of memory into the accumulator, as well as setting the negative and zero flags.
All eight addressing modes can be used with the LDA operator:
|immediate||LDA #8||load $8 into accumulator|
|zero page||LDA $00||load accumulator from zero page address $00|
|zero page, X||LDA $06, X||load accumulator from zero page with address calculated from $06 adding content of X|
|absolute||LDA $1000||load accumulator from address $1000|
|absolute, X||LDA $1000, X|
