Figure 2.1 CPU Register
Figure 2.1 shows the CPU registers. The CPU has 13 registers. Of these, R0, R1, R2, R3, A0, A1 and FB
comprise a register bank. Two sets of register banks are provided.
2.1 Data Registers (R0, R1, R2 and R3)
R0 is a 16-bit register for transfer, arithmetic and logic operations. The same applies to R1 to R3. The
R0 can be split into high-order bit (R0H) and low-order bit (R0L) to be used separately as 8-bit data
registers. The same applies to R1H and R1L as R0H and R0L. R2 can be combined with R0 to be
used as a 32-bit data register (R2R0). The same applies to R3R1 as R2R0.
