Figure 2.1 CPU Registers
2.1 Data Registers (R0, R1, R2, and R3)
2.2 Address Registers (A0 and A1)
Figure 2.1 shows the CPU Registers. The CPU has 13 registers. Of these, R0, R1, R2, R3, A0, A1, and FB
configure a register bank. There are two register banks.
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 analogous to R2R0.
The A0 register 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, A1 and A0 can be combined for use as a 32-bit address register (A1A0).
