6.8 I2C_ERR_01

I2C module may hold the SDA line low when an SMBUS quick command is issued

Revisions Affected

B

Details

IF the I2C module is in target mode AND configured for SMBUS ; AND IF the bus controller issues an SMBUS quick command addressed to the device with the R/W bit set to read, THEN the I2C module may hold the SDA line low preventing the STOP condition from completing successfully

Workaround

Load data into the I2C module transmit FIFO with the MSB set to 1 before the address ACK is completed to prevent the I2C module from driving the SDA line low.
