299 | * | |
300 | * During I2C reads, the KS0127 only samples for a stop condition | |
9875c0fb | 301 | * during the place where the acknowledge bit should be. Any standard |
fbe60daa MS |
302 | * I2C implementation (correctly) throws in another clock transition |
303 | * at the 9th bit, and the KS0127 will not recognize the stop condition | |
304 | * and will continue to clock out data. | |
305 | * | |
306 | * So we have to do the read ourself. Big deal. | |
