9. REGISTER FILE (RF)
The register file is a group of registers that mainly control the CPU peripheral circuits. The register file has
a capacity of 128 words
× 4 bits. However, peripheral circuit addresses are actually allocated to the high-order
64 nibbles (00H-3FH) and addresses 40H-7FH of the currently selected bank of data memory to the low-order
64 nibbles (40H-7FH).
This means that 40H-7FH of each bank of data memory belongs to both the data memory address space
and the register file address space.
In the assembler, the control register file is allocated to 80H-BFH.
