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_mask

A 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_SUCCESS	The operation was succesful.
ALT_E_ERROR	The 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.
