addressed by the address pointer. The address ranges are X 0 to X 127 (7Fh) and Y 0 to
Y 5 (5h). Addresses outside of these ranges are not allowed. In vertical addressing mode
(V = 1), the Y address increments after each byte (see
(Y = 4), Y wraps around to 0 and X increments to address the next column. In horizontal
addressing mode (V = 0), the X address increments after each byte (see
the last X address (X = 127), X wraps around to 0 and Y increments to address the next
