308 | * An explanation from kayork@mail.utexas.edu: | |
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. | |
