1.3 Register Configuration
Chapter 1 Overview
The central processing unit (CPU) contains the 13 registers shown in Figure 1.3.1. Of these registers, R0,
R1, R2, R3, A0, A1, and FB each consist of two sets of registers configuring two register banks.

*1
The data registers (R0, R1, R2, and R3) consist of 16 bits, and are used primarily for transfers and
arithmetic/logic operations.
Registers R0 and R1 can be halved into separate high-order (R0H, R1H) and low-order (R0L, R1L) parts
for use as 8-bit data registers. For some instructions, moreover, you can combine R2 and R0 or R3 and
R1 to configure a 32-bit data register (R2R0 or R3R1).
