(7)X, Y- address counter

X, Y-address counter is a 9-bit counter which gives the address of the internal display data RAM. It is necessary to set the X-address counter of the three upper bits, and the Y-address counter of the six ￿lower bits using differing instructions.

X-address counter

Address counter X is a simple register that is not provided with a count function. The address is set by instruction.
