* \brief
|
|
* Provides a high level interface for interacting with the Cypress power
|
|
* management and system clock configuration. This interface abstracts out the
|
|
* chip specific details. If any chip specific functionality is necessary, or
|
|
* performance is critical the low level functions can be used directly.
