FIFO Signal Timing—Receiving
When a frame is ready to send from the MAX2986 to
the external host, the MAX2986 asserts MIIRXDV after
an IFG (which is about 0.96μs), while there is no trans-
mission session in progress (with respect to MIICRS). A
receive process cannot start while a transmission is in
progress.
While the MAX2986 keeps MIIRXDV high, it sends 1
byte of data on MIIDAT for each positive edge on
BUFRD
. The first 2 bytes represent frame length in
MSB-first format. After the last byte of data is received,
the MAX2986 resets MIIRXDV. The direction of bidirec-
tional data pins is controlled through
BUFCS
and
BUFRD
pins. The MAX2986 enables data output drivers
when BUFCS = 0 and BUFRD = 0. The interactions
between the external host and the MAX2986 baseband
is shown in Figure 13 and the overall receive timing of
the buffering interface is illustrated in Figure 14, with
details in Figure 15 and Table 8.
