SRU Programming

Any of the serial port's signals can be mapped to digital applications inter-
face ( ) pins through the signal routing unit (SRU) as shown in
DAI_Px
Table 10-3. For more information, see Chapter 9, Digital Applica-
tion/Digital Peripheral Interfaces.

SPORTs 6 and 7 receive their clocks from other routed sources but
cannot route their own clocks to other SPORTs or other peripher-
als internally through the SRU. If SPORTs 6 and 7 are needed
externally, they have to be routed through the DAI pins.
