Work around
Set the communication speed to match the
slowest device on the bus. This ensures that no
slave device will perform clock stretching.
It
communication speed to match the device being
addressed by modifying the BRG register.
However, the behavior of slower slave devices
must be understood and speed adjustments made
such that no slave performs clock stretching.
