Data Memory (RAM)
The data memory space is assigned to RAM and special function registers (SFRs). Data Memory
is located in a different address space from program memory.
The data length is 4 bits (1nibble), and a bank unit is 256 nibbles. The data memory uses two bank
areas: one for the EEPROM and SFR areas, in Bank 0; the other for RAM, including the stack, in
Bank 7.
The following figure shows the address space of data memory.
