* Name: stm32_setup_overcurrent
|
||||
*
|
||||
* Description:
|

* Setup to receive an interrupt-level callback if an overcurrent condition is
|
||||
* detected.
|
||||
*
|
||||
* Input Parameter:
|
||||
* handler - New overcurrent interrupt handler
|
||||
* arg - The argument provided for the interrupt handler
|
||||
*
|
||||
* Returned value:
|
||||
* Zero (OK) is returned on success. Otherwise, a negated errno value is returned
|
||||
* to indicate the nature of the failure.
