If the Client is reading then
response data will be
obtained from this table.
If the Client is writing,
incoming data will be
stored in this array
Address1 corresponds to
offset 0 (1
st
location) in the
array. If the Client reads
%R15 then the driver
responds with data from
element 14 of the array.
This is a Server. It
responds to polls but
does no active work
itself.
This Map Descriptor can be
used to respond to a poll that
reads and writes to addresses 1
to 1000. If a poll attempts to
read data at address 1001,
then if no other Map
Descriptor covers that address
space, a “no datas” response
will be sent.
This Map Descriptor will be
used to process Client
read/writes of Register
(%R) data.
