9. SMBUS Timeout Register Setting (SMBUS_TIMEOUT) Does Not Assert

Description

The SMBus timeout register setting (SMBUS_TIMEOUT) does not assert when the device exceeds the 35 ms maximum value prescri-

bed by the standard.

Impact

If SMBUS_TIMEOUT is mapped to affect the hardware interrupt pin (INTR#), the SDA bus will not be released as expected and re-

quired by the SMBus standard.

Workaround

None. Avoid reliance on the SMBus timeout feature.

Resolution

This erratum will be fixed in the next silicon revision.
