Now our project encountered a problem: the k64 cpu want to
communicate with micrel ksz8863 through SMI mode to visit the internal register
from 0~198. According to the SMI mode visit protocol, the different is below:

PAGE 1172 in attached k64 cpu
datasheet:

 

 

OP= 00 WRITE/OP=11 READ

 

And in 8863 datasheet (page33 ):

OP = 00 read/write function

 

It seems the two datasheet about
the OP is contradictory.

 

Do you have any guidance or
information according to your experience?
