Figure 1. Program Memory Organization
Data Memory (RAM)
1. Architecture
The static data memory (RAM) used to store data is arranged as 64

4 bits. The data memory can be
addressed directly or indirectly. The organization of the data memory is shown in Figure 2.

Figure 2. Data Memory Organization
The first sixteen addresses (00H to 0FH) in the data memory are known as the working registers
(WR). The other data memory is used as general memory and cannot operate directly with immediate
data. The relationship between data memory locations and the page register (PAGE) in indirect
addressing mode is described in the next section.
