4.3 TSMP (TS Multiplexing Pins) on MPP
The TS interface can be configured to one of five modes:
One or two serial in interfaces
One or two serial out interfaces
Serial in and serial out interface
Parallel in interface
Parallel out interface
In parallel in or serial in mode, all TS signals are inputs.
In parallel out or serial out mode, all TS signals are outputs.
Table 28 summarizes the TS port pins multiplexing.
