C-bus supply current
more clocks ensures the slave state machine returns to a known, idle state since the
protocol calls for eight data bits and one ACK bit. It does not matter when the slave state
machine finishes its transmission, extra clocks will be recognized as STOP conditions.
The PCAL6416A SCL pin is an input only. If SCL is stuck LOW, then only the bus master
or a slave performing a clock stretch operation can cause this condition.
With careful design of the bus master error recovery firmware, many I
problems can be avoided.
