I'm a DFAE in Japan .
When my customer runs self test procedure in ADXL372 datasheet page 24, ST_DONE bit is set to 1 after 300ms.
But, judging from Table1 in B-sample errata datasheet RevB on 2021/3/24 (attached) , he needs to follow the steps described in ERRATA to run self test.
However, when he run self test steps described, ST_DONE is NOT set to 1 .
Does this self test procedure in ERRATA work correctly?
why is ST_DONE bit NOT set to 1 after 300ms?
