We apologize for the delay, thank you very much for your patience.
The CLKL (Low Speed Bus Clock) may help to solve this inconvenience, it is important to let you know that the CLKL is changed, it is also necessary to change the set value of the I2CBC register accordingly. You can review this information in the Intel® Platform Controller Hub EG20T Datasheet, in section 15.2, on page 545; all the I2CBC register information is available in section 184.108.40.206, page 561.
Please refer to the bits I2CMSTA, I2CRSTA, I2CBMTO, and I2CESRTO, these bits may help you to delay data processing. The information related to these bits is stated in sections 220.127.116.11, 18.104.22.168, and 22.214.171.124; on pages 557, 567, and 571 of the cited datasheet.
The supported Operating Systems by the Intel® Platform Controller Hub EG20T are:
Microsoft Windows* XP SP3,
Microsoft Windows Embedded Standard 2009,
Microsoft Windows Embedded Standard 7,
Microsoft Windows Embedded POS Ready 2009,
Microsoft Windows 7,
Microsoft Windows Embedded CE 6.0 R3,
