* @defgroup HAL HAL Driver
|
|
* @brief Hardware Abstraction Layer.
|
|
* @details The HAL (Hardware Abstraction Layer) driver performs the system
|
|
* initialization and includes the platform support code shared by
|
|
* the other drivers. This driver does contain any API function
|
|
* except for a general initialization function @p halInit() that
|
|
* must be invoked before any HAL service can be used, usually the
|
|
* HAL initialization should be performed immediately before the
|
|
* kernel initialization.<br>
|
|
* Some HAL driver implementations also offer a custom early clock
|
|
* setup function that can be invoked before the C runtime
|
|
* initialization in order to accelerate the startup time.
