3.4 DN4 Card Configuration Registers
This section provides hardware register details for the card.
3.4.1 Host Register Layout
The channel has its own set of registers, located in I/O space.
Note
Upon card power up, or after a physical reset from the system, it
typically takes 1 second for the channel to initialize (though it is
recommended that applications wait up to 2 seconds). Initialization can
be confirmed by monitoring the LEDs or by reading the FamilyID
register, as described in Section C.1.1, Verify Card Presence.
