Dear Sirs

I'm trying to develop SPI code for TM4C1294KCPDT/ADS1261 interface.  As a starting point, I'm using the code provided in the spo_master.c located in the C:\TI\TivaWare_C_Series-2.1.4.178\examples\peripherals\ssi folder from TI.  In this file, the code configure PA4 as the RX and PA5 as the TX.  However, the TM4C1294KCPDT data sheet (June 18, 2014) page 1226 says "Note that for the QSSI module, when operating in Legacy Mode, SSInXDATA0 functions as SSInTX and SSInXDATA1 functions as SSInRX".  Which is correct?
