| 309 | * |
| 310 | * During I2C reads, the KS0127 only samples for a stop condition |
| 311 | * during the place where the acknoledge bit should be. Any standard |
| 312 | * I2C implementation (correctly) throws in another clock transition |
| 313 | * at the 9th bit, and the KS0127 will not recognize the stop condition |
| 314 | * and will continue to clock out data. |
| 315 | * |
| 316 | * So we have to do the read ourself. Big deal. |
