8.5.5 Register File
The register file consists of 32 8-bit general purpose working registers with single clock cycle access time. The register file supports the following input/output schemes:
- One 8-bit output operand and one 8-bit result input
- Two 8-bit output operands and one 8-bit result input
- Two 8-bit output operands and one 16-bit result input
- One 16-bit output operand and one 16-bit result input
Six of the 32 registers can be used as three 16-bit address register pointers for data space addressing, enabling efficient address calculations.
The register file is located in a separate address space and is therefore not accessible trough instructions operation on data memory.
