clr_alarms (0x00)
Clear Alarms Register: This register is used to clear alarms caused by exceeding a programmed limit. Writing a one to any bit in this register will cause its
respective alarm to be cleared. The one written to this register is automatically cleared when its respective alarm is cleared.
