Data Memory - Lower 128 byte
Data memory $00 to $FF is the same as 8052
The address $00 to $7F can be accessed by direct and indirect addressing modes.
Address $00 to $1F is register area.
Address $20 to $2F is memory bit area.
Address $30 to $7F is for general memory area.
Data memory - Higher 128 byte
The address $80 to $FF can be accessed by indirect addressing mode only.
Addressing $80 to $FF is data area.
Data Memory - Expanded 768 bytes
From external address $0000 to $02FF is the on-chip expanded RAM area, total 768 bytes. This area can be
accessed by external direct addressing mode only (by instruction MOVX).
