Zero page addressing

Zero page addressing is a form of memory addressing that uses only the zero page of the 6502 microprocessor. It takes advantage of the memory addresses of the zero page ($0000 to $00FF by leaving off the first two zeros and thus saving a byte.

Zero page addressing is written in 6502 ASM by simply leaving off the first two zeros in the memory address.

LDA $09

This would load the value in memory location $0009 into the accumulator.
