Figure 2.1 shows the CPU registers. The register bank is comprised of 7 registers (R0, R1, R2, R3, A0, A1
and FB) out of 13 CPU registers. Two sets of register banks are provided.
The R0, R1, R2 and R3 registers are 16 bit registers for transfer and arithmetic/logic operations.
The R0 and R1 registers can be split into high-order bits(R0H, R1H) and low-order bits (R0L, R1L) to be
used seperately as 8-bit data registers. Conversely, R2 and R0 can be combined with R2 to be used as a
32-bit data register (R2R0). The same applies to R1 and R2.
The register A0 consists of 16 bits, and is used for address register indirect addressing and address register
relative addressing. They also are used for transfers and arithmetic/logic operations. A1 is the same as A0.
In some instructions, registers A1 and A0 can be combined for use as a 32-bit address register (A1A0).
