TrimOK: 1 if device passed both 105degC and m40degC test successfully, 0 if one of the tests
is not passed successfully
DieChip: 1 if die chipping is present, 0 is not die chipping is present. Note that DieChip will
only be valid during NRM.
TO: 1=a Watchdog time-out and a master reset occurred. 0=no Watchdog time-out
occurred, or after Power-On, or after a WDT command
POR: 1=a POR occurred, 0=a POR has not occurred. To detect subsequent Power-On-Resets,
the POR-bit shall be cleared right after Power-On.
