Data Sheet Errata for Product Revision B
SMBUS Timeout Register Setting (SMBUS_TIMEOUT) Does Not Assert
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.
