| * Some PMBus chips respond with valid data when trying to read an unsupported | |
| * register. For such chips, checking the status register is mandatory when | |
| * trying to determine if a chip register exists or not. | |
| * Other PMBus chips don't support the STATUS_CML register, or report | |
| * communication errors for no explicable reason. For such chips, checking | |
| * the status register must be disabled. | |
