Indirect Addressing

Direct page indirect → [dp]

Assigns data address to use for accomplishing command which

sets memory data (or pair memory) by Operand.

Also index can be used with Index register X,Y.

Y indexed indirect → [dp]+Y

Processes memory data as Data, assigned by the data [dp+1][dp]

of 16-bit pair memory paired by Operand in Direct page plus Y-

register data.
