E.11 Indirect Indexed Indirect indexed (also known as post-indexed) addressing takes a single operand which gives the zero page address of the least significant byte of a 16-bit address which is then added to the Y register to give the target address. For example, if the operand is bb, 00bb is xx and 00bb + 1 is yy, then the data can be found at yyxx. An example of this addressing mode is AND ($12),Y. Figure E-19. Indirect indexed addressing. 44

E.11 Indirect Indexed
Indirect indexed (also known as post-indexed) addressing takes a single operand which
gives the zero page address of the least significant byte of a 16-bit address which is then
added to the Y register to give the target address. For example, if the operand is bb, 00bb is
xx and 00bb + 1 is yy, then the data can be found at yyxx. An example of this addressing
mode is AND ($12),Y.
