8. REGISTER FILE (RF)
The register file is a register that mainly sets the conditions of the peripheral hardware.
8.1 Configuration of Register File
8.1.1 Configuration of register file
Figure 8-1 shows the configuration of the register file.
As shown in this figure, the register file consists of 128 nibbles (128
×
4 bits). Like the data memory, the
register file is assigned addresses in 4-bit units, with row addresses 0H-7H and column addresses 0H-0FH.
Addresses 00H-3FH of the register file are called a control register.
Figure 8-1. Configuration of Register File
8.1.2 Register file and data memory
Figure 8-2 shows the relationships between the register file and data memory.
As shown in this figure, addresses 40H to 7FH of the register file overlaps the data memory.
It seems from the program as if addresses 40H to 7FH of the data memory exist at addresses 40H-7FH of
the register file.
