USCI Module

Function

Tbuf parameter violation in I2C multi-master mode

Description

In multi-master I2C systems the timing parameter Tbuf (bus free time between a stop condition and the following start) is not guaranteed to match the I2C specification of 4.7us in standard mode and 1.3us in fast mode. If the UCTXSTT bit is set during a running I2C transaction, the USCI module waits and issues the start condition on bus release causing the violation to occur.
Note: It is recommended to check if UCBBUSY bit is cleared before setting UCTXSTT=1.

Workaround

None
