Hello,

My program uses two FSMC_Bank1 for the tft screen and memory (62WV51216ALL), NORSRAM3 is used for memory and NORSRAM4 for the screen, a problem has been identified that when accessing NORSRAM3 (memory), the CS signal (FSMC_NE3) goes low and remains so permanently. The same thing happens with the signal for the CS screen (FSMC_NE4) and when garbage from points are written to the memory on the screen. How can I return the CS signals to their normal position after accessing the right data source?
