This pin’s description is the same as that given in
Receive (Interface), Tri-State.
The input on this pin is from a MAC. When the signal on this pin
is logic:

SRD0 is the least-significant bit and SRD3 is the
most-significant bit of the MII receive data nibble.
While the ICS1892 asserts RXDV, the ICS1892 transfers the
receive data signals on the SRD0–SRD3 pins to the
MAC/Repeater Interface synchronously on the rising edges
of SRCLK.
Low, the MAC indicates that it is not in a tri-state condition.
High, the MAC indicates that it is in a tri-state condition. In
this case, the ICS1892 acts to ensure that only one PHY is
active at a time.
STD0 is the least-significant bit and STD3 is the
most-significant bit of the MII transmit data nibble received
from the MAC/repeater.
While the ICS1892 asserts TXEN, the signals on the
STD0–3 pins are sampled by the ICS1892 synchronously on
the rising edges of STCLK.
