Is there any way to control the External memory pins from registers through code, or are these four pins solely controlled by the MCU internally? I'm not using external memory, but I could use a couple more general output pins. Anyway to make use of these?

Hi,

I suppose you are speaking about EMI control pins (EMI_BWR_WRLn, EMI_WRHn, EMI_ALE and EMI_RDn )

These pins couldn't be used as GPIO pins, they are only controlled by the EMI unit when doing external memory access.
