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 configured as two register banks.
Figure 1.3.1 CPU Register Configuration
1.3.1 Data Registers (R0, R0H, R0L, R1, R1H, R1L, R2, and R3)
The data registers (R0, R1, R2, and R3) each consist of 16 bits and are used primarily for transfers and
arithmetic/logic operations.
Registers R0 and R1 can be divided into separate high-order (R0H, R1H) and low-order (R0L, R1L)
parts for use as 8-bit data registers. For some instructions, moreover, R2 and R0 or R3 and R1 can be
combined to configure a 32-bit data register (R2R0 or R3R1).

Note: * These registers configure register banks.This register
bank consists of two sets.
