Loopback Operation
Each lane of the PI2EQX5864C provides a loopback mode for test purposes which is controlled by a strapping pin and I
bit. The LB# pin controls all lanes together. When this pin is high normal data mode is enabled. When LB# is low the loopback
mode is enabled. The fi gure below diagrams this operation. Loopback is not intended to be dynamically switched, and the normal
system application is to initialize to one confi guration or the other.
The Loopback mode can also support mux/demux operation. Using I
minimize power and unnecessary noise.
I
The PI2EQX5864C I
mode. The data byte format is 8 bit bytes. The bytes must be accessed in sequential order from the lowest to the highest byte with
the ability to stop after any complete byte has been transferred. Address bits A4, A1 and A0 are programmable to support multiple
chips environment. The data is loaded until a Stop sequence is issued.
