Figure 7. Receive Behavior of the MII Interface
MII Signal Timing—Receiving
When a frame is ready to send from the MAX2986 to
the external host, the MAX2986 asserts MIIRXDV after
IFG (which is about 0.96μs), while there is no transmis-
sion session in progress (with respect to MIICRS).
Note:
The receive process cannot start while a trans-
mission is in progress.
While the MAX2986 keeps MIIRXDV high, data is sam-
pled synchronously with respect to MIICLK from the
MAX2986 through MIIDAT. After the last byte of data is
received, the MAX2986 resets MIIRXDV.
Receive timing of the MII interface is illustrated in
Figure 7, with details in Figure 8 and Table 4.
