* communication or command errors. |
|
* |
|
* 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. |
