Hi Team,
There's a question about ethernet chip, and I wanna consult.
Strap is Configurated MII mode. And I can read almost all registers(inculde MMD1), but PMA_EXT2 and PMA_CTRL2.
I can read data from PMA_CTRL1 and PMA_EXT1. But why I can't read PMA_EXT2 and PMA_CTRL2?
Configurating PMA_CTRL2 to choose master or slave mode, this's so important to me.
So why PMA_CTRL2 cannot be read? Did I miss anything？
The photo1 is read data from PMA_CTRL1, and get 0000_0000_0011_1101(correct).
The photo2 is read data from PMA_CTRL2, but get FFFF.
THANKS!
