Software Reference

4.1

DRAM

For DDR SDRAM Sizes and Configurations, see theIntel

80332 I/O Processor Developer’s

Manual. This section also contains multiple examples of Address Register Programming.

See the Intel

80332 I/O Processor Design Guide, section 8, table 34 for supported DDR333 and

DDR-II configurations.

For all registers relating to DRAM and other MCU related registers, see the Intel

80332 I/O

Processor Developer’s Manual.

4.2

Components on the Peripheral Bus

The 80332 has a peripheral bus which contains the following peripheral devices:

•

Flash ROM

•

CPLD

•

Audio Buzzer

•

Rotary Switch

•
