1. Overview

Low power

consumption

Low power consumption

facilities

 Module stop function

 Four low power consumption modes

Sleep mode, all-module clock stop mode, software standby mode, and deep software

standby mode

Interrupt

Interrupt controller

(ICUC)

 Interrupt vectors: 256

 External interrupts: 16 (pins IRQ0 to IRQ15)

 Software interrupts: 2 sources

 Non-maskable interrupts: 7 sources

 Sixteen levels specifiable for the order of priority

 Method of interrupt source selection:

The interrupt vectors consist of 256 vectors (208 sources are fixed. The remaining 135

vectors are selected from among the other 48 sources.)

External bus extension

 The external address space can be divided into four areas (CS0 to CS3), each with

independent control of access settings.

Capacity of each area: 2 Mbytes (CS0 to CS3)

A chip-select signal (CS0# to CS3#) can be output for each area.

Each area is specifiable as an 8- or 16-bit bus space.

The data arrangement in each area is selectable as little or big endian (only for data).

 Bus format: Separate bus, multiplex bus

 Wait control

 Write buffer facility

DMA

DMA controller

(DMACAa)

 8 channels

 Three transfer modes: Normal transfer, repeat transfer, and block transfer

 Request sources: Software trigger, external interrupts, and interrupt requests from

peripheral functions

Data transfer controller

(DTCa)

 Three transfer modes: Normal transfer, repeat transfer, and block transfer

 Request sources: External interrupts and interrupt requests from peripheral functions
