DS90UH940-Q1: Can we use register 0x25 to read forward channels CRC error ?

Hello PYTsai,

section 7.3.14 talks about BIST Mode. If you are using BIST, then yes, you can use register 0x25 for counting BIST errors.

CRC errors are only a function of the back channel. So, CRC counter can be found only on the SER.
