7.8.4.4 TWO MULTIPLEXED CHANNELS WITH DYNAMIC FRAMES. With this configu-
ration (see Figure 7-26), there are two multiplexed channels. Each channel has 16 entries
for transmit data and strobe routing and 16 entries for receive data and strobe routing. In
each RAM, one of the partitions is the current-route RAM, and the other is a shadow RAM
used to allow the user to change the serial routing. After programming the shadow RAM, the
user sets the CSRx bit of the associated channel in the SI CR. When the next frame sync
arrives, the SI will automatically exchange the current-route RAM for the shadow RAM.
Refer to 7.8.4.7 SI RAM Dynamic Changes for more details on how to dynamically change
the channel's route. This configuration should be chosen when two TDMs are required and
the routing on each TDM may need to be changed dynamically.
