1. Overview

1.1 Features

The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group of single-chip MCUs

incorporate the R8C CPU core, which implements a powerful instruction set for a high level of efficiency and

supports a 1 Mbyte address space, allowing execution of instructions at high speed. In addition, the CPU core

integrates a multiplier for high-speed operation processing.

Power consumption is low, and the supported operating modes allow additional power control. These MCUs are

designed to maximize EMI/EMS performance.

Integration of many peripheral functions, including multifunction timer and serial interface, helps reduce the

number of system components.

The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group have data flash.

1.1.1 Applications

Household appliances, office equipment, audio equipment, consumer products, etc.

Central Processing Unit (CPU) 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. R0 can be split into high-order bits (R0H) and low-order bits (R0L) to be used separately as 8-bit data registers. R1H and R1L are analogous to R0H and R0L. R2 can be combined with R0 and used as a 32-bit data register (R2R0). R3R1 is analogous to R2R0. 2.

Interrupts are disabled when the I flag is set to 0, and are enabled when the I flag is set to 1. The I flag is set to 0 when an interrupt request is acknowledged. 2.8.8 Stack Pointer Select Flag (U) ISP is selected when the U flag is set to 0; USP is selected when the U flag is set to 1.

For example, a 48-Kbyte internal ROM area is allocated addresses 04000h to 0FFFFh. The fixed interrupt vector table is allocated addresses 0FFDCh to 0FFFFh. The starting address of each interrupt routine is stored here.
