Hello Team,
I have received a question from my customer who wants to know what does the Link Layer chip populate bits 0-15 with when we read the PHY Access register ?. The datasheet is not clear on this when a read occurs, only a write.
The question from the customer is as follows:
" What I would like to know is when we do a read of the PHY access register, what is returned in bits 0-15? I know bits 16-31 are the address that was read from the PHY and data read from the PHY "
From what I understand the bits from 0-15 should populate something like
0 1 2- 3 4 - 7 8-15
1/0 0 (reserved ?) Address to be accessed Data to be written
Thank you for your time,
Sincerely,
Kishen
