START flag. When this bit is set in slave mode, the hardware checks the I
and generates a START condition if the bus is free or after the bus becomes free.
If the device operates in master mode it will generate a repeated START
condition.
STOP flag. If this bit is set in a master mode a STOP condition is generated.
A STOP condition detected on the I
in slave mode in order to recover from an error condition. In this case no STOP
condition is generated to the I
SCL lines and switches to the not selected receiver mode. The STOP flag is
cleared by the hardware.
