TM4C129CNCPDT: EPI with SRAM - remaining pins

Part Number: TM4C129CNCPDT

Tool/software:

TM4C team,

If a customer uses the EPI to interface to an SRAM using an 8051 style 16 bit bus that multiplexes addr/data, they end up using 23 pins total for EPI.  The EPI module uses up to 32 pins.  Can they use the remaining 9 pins that would have been for EPI for other functions, like GPIO?

I'm pretty sure the answer is yes, but want to be sure.

Thanks,
Darren

    Hi Darren,

      Yes, you can use the remaining pins for GPIO purpose.
