Texas Instruments TM4C1294NCPDT User Manual

parentheses is the encoding that must be programmed into the PMCn field in the GPIO Port Control
(GPIOPCTL) register (page 787) to assign the QSSI signal to the specified GPIO port pin. For more
information on configuring GPIOs, see “General-Purpose Input/Outputs (GPIOs)” on page 742. Note
that for the QSSI module, when operating in Legacy Mode, SSInXDAT0 functions as SSInTX and
SSInXDAT1 functions as SSInRX.
