Accumulator Addressing

Accumulator Addressing is a special type of Implied Addressing that only addresses the accumulator.

Examples

This example uses Accumulator Addressing to transfer the value stored in the accumulator to the X register.

0001:0A        ASL             ; Bit-shift the accumulator left.

Opcodes

There are only a couple of opcodes that only address the Accumulator:

ASL

LSR
