Function Documentation

◆ alt_reset_event_clear()

ALT_STATUS_CODE alt_reset_event_clear ( uint32_t  event_mask)

Clears the reset and timeout events that caused the last reset.

Parameters
event_maskA mask of the selected reset and timeout events to clear in the Reset Manager stat register. The mask selection can be formed using the ALT_RESET_EVENT_t enumeration values.
Return values
ALT_E_SUCCESSThe operation was succesful.
ALT_E_ERRORThe operation failed.

◆ alt_reset_event_get()

uint32_t alt_reset_event_get ( void  )

Gets the reset and timeout events that caused the last reset.

The ALT_RESET_EVENT_t enumeration values should be used to selectively examine the returned reset cause(s).

Returns
A mask of the reset and/or timeout events that caused the last reset.
