| * |
| * During I2C reads, the KS0127 only samples for a stop condition |
| * during the place where the acknowledge bit should be. Any standard |
| * I2C implementation (correctly) throws in another clock transition |
| * at the 9th bit, and the KS0127 will not recognize the stop condition |
| * and will continue to clock out data. |
| * |
| * So we have to do the read ourself. Big deal. |
