[ DS90UB927-Q1 & DS90UB928-Q1 ] BIST Mode and "DES Error"(0x0C[1])
Hi,
<Q1>:
Can you please elaborate "DES Error"(0x0C[1]) of DS90UB927?
The description says that "CRC error during BIST...". As my understanding, CRC is used for the BIST of back-channel communication.
However, we have another bit to indicate "BIST CRC Error". What is the difference?
Are there any relation to 0x03[7] "Back Channel CRC Checker Enable" bit?
<Q2>:
Is it the possible case that this "DES Error" is triggered without UB927 and UB928 going to BIST mode?
<Q3>:
The drawing below expresses my understanding of BIST report. Correct?
Thanks,
Ken
