The module ID signals, which are only valid when IDREQ_ is asserted,
indicate the type of the serial module that is installed on either Port 3 or
Port 4. The following table shows how to interpret the MID3-MID0
signals:
Note
Because IDREQ_ and MID3-MID0 signals go through the
P2MX (P2 multiplexing) function used on
MVME2600/2700 series modules configured for the
MVME761-type transition module, software must wait for
the MID3-MID0 to become valid after asserting IDREQ_.
The waiting time should be about 4 microseconds because
the sampling rate is about 1.6 microsecond with a 10MHz
MXCLK clock.
