KTT20/pITX Software Guide

For the I

part some restrictions are valid:

Do not access board devices (e.g. temperature sensor - this device has an own interface).

Especially this part should be used for external components on the digital I/O (GPIO) or mini

PCI Express

connector.

Some datasheets present the device address as a shifted value (e.g. EEPROM address =

0xA0). Use instead the unshifted value (e.g. real EEPROM address = 0x50).

Bus 1 allows access to the DVI

DDC lines. Do not overwrite the EDID EEPROM.
