Feature

Description

Bus controller

• Address space can be partitioned into eight areas, with independent bus

specifications in each area

• Chip select output available for areas 0 to 7

• 8-bit access or 16-bit access selectable for each area

• Two-state or three-state access selectable for each area

• Selection of two wait modes

• Number of program wait states selectable for each area

• Direct connection of burst ROM

• Direct connection of up to 8-Mbyte DRAM (or DRAM interface can be used

as interval timer)

• Bus arbitration function

DMA controller

(DMAC)

Short address mode

• Maximum four channels available

• Selection of I/O mode, idle mode, or repeat mode

• Can be activated by compare match/input capture A interrupts from 16-bit

timer channels 0 to 2, conversion-end interrupts from the A/D converter,

transmit-data-empty and receive-data-full interrupts from the SCI, or external

requests

Full address mode

• Maximum two channels available

• Selection of normal mode or block transfer mode

• Can be activated by compare match/input capture A interrupts from 16-bit

timer channels 0 to 2, conversion-end interrupts from the A/D converter,

external requests, or auto-request

16-bit timer,

3 channels

• Three 16-bit timer channels, capable of processing up to six pulse outputs or

six pulse inputs

• 16-bit timer counter (channels 0 to 2)

• Two multiplexed output compare/input capture pins (channels 0 to 2)

• Operation can be synchronized (channels 0 to 2)

• PWM mode available (channels 0 to 2)

• Phase counting mode available (channel 2)

• DMAC can be activated by compare match/input capture A interrupts

(channels 0 to 2)
