devices. Test the BB until it becomes “0” to check that the SCL pin of a serial bus interface circuit is released.
Test the LRB until it becomes “1” to check that the SCL line on a bus is not pulled-down to the low level by
other devices. After confirming that a bus stays in a free state, generate a start condition with procedure "15.6.2
