Submitted by: Muhammad

☛ Only 16 bytes of the 128 bytes of RAM are bit addressable.
☛ The bit addressable RAM locations are 20H to 2FH.
☛ They are addressed as 0 to 127 (decimal) or 00 to 7F.
☛ Also the internal RAM locations 20 to 2FH are both byte and bit addressable.
☛ These 16 bytes can be by single bit instructions using only direct addressing mode.
