(set bit 2) to report that the module is parameterized. Assoonasthe bit has

status register for monitoring purposes.
This status bit remains set as long as operation of the module is "normal". It
is deleted when a supply voltage failure occurs or the S5 initiates a RESET
(i.e., the parameterization is lost).
