Clause 33 (MDC/MDIO) questions


On page 84. second section after the table 33-21.
'An address frame should be followed "IMMEDIATELY" by its
associated write, ..........'

Can you define "immediately"? is there a max IFG ?
Or it's just saying the PHY device is expecting a data frame after
an address frame?

Will it break anything if we send two address frames without any
data frame in between?
I expect that the second register address will overwrite the first
register address in the PHY's local address table without breaking
