Hardware Ports: General Page 2 - 7

Channel Attention Port - The Channel Attention Port is your means of

informing the RF3880 adapter that a command is ready to be executed. The

value you write to this port tells the adapter what kind of Command Structure

to expect. Before you write to the Channel Attention Port you must set-up the

appropriate Command Structure in the system memory space you will be

directing the adapter to read.

Status Port - This port is used to read status from the adapter. There are two

types of status that can be read: General Status—returned after a command

completes during normal operation; and Reset Status—returned during board

self-test at reset or power-up.

Reset Port - With the Reset Port you are able to initiate, through software, a

reset identical to a hardware reset.
