TM4C1294NCPDT: Used for other pin functions when EPI is not used

Part Number: TM4C1294NCPDT

Hi, 

Regarding the unconnected EPI0S20 to 27, EPI0S32 and later pins, if they are pins that can be assigned other functions such as GPIO, I2C, UART, can they be assigned to use those functions?

Are there any problems with EPI0S bus control?

Thanks,

Conor

      Which mode will be you operating for EPI interface? You seem to be using SDRAM, correct? If this is the case, you can use these pins for other functions like GPIO, I2C or UART.
