Best Answer

This 8 bit register contains the most-significant byte of the address to be used in the direct addressing mode. The contents of this register are concatenated with the byte following the direct addressing mode operation code to form the 16-bit effective address. The direct page register contents appear as bits A15 through A8 of the address.
