Field
Bits 0:31
Description
MBSx: MBIST status
0: Failed MBIST execution
1: No fault detected during the BIST execution
NOTE
A BIST counts as successfull when no fault was detected during execution
(see MBSL, MBSH) and its execution is finished (see MBEL, MBEH).
42.4.3.8 STCU MBIST Status High Register (STCU_MBSH)
The STCU_MBSH register includes the results corresponding to the execution of each MBIST. The
STCU_MBSH register is automatically set following the completion of the MBIST run.
