Central Processing Unit (CPU)
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. There are two register banks.

Data Registers (R0, R1, R2 and R3)
The R0 register consists of 16 bits, and is used mainly for transfers and arithmetic/logic operations. R1 to R3 are
the same as R0.
The R0 register can be separated between high (R0H) and low (R0L) for use as two 8-bit data registers.
R1H and R1L are the same as R0H and R0L. Conversely, R2 and R0 can be combined for use as a 32-bit data
register (R2R0). R3R1 is the same as R2R0.
