K70 Pin mux with NAND flash

[chiranjeevn]

Hi,

    I m routing the signals of K70 processor to NAND flash.

    In  K70 Processer the Pin PTC17 and PTC18 contains NFC_CE0 and NFC_CE1.

      In Tower kit the PTC17 is given to NAND flash .I would like to know that if i use PTC18 is given to NAND flash the signal function is same      between NFC_CE0 and NFC_CE1 or different?please assist me..............

Hi,

NFC_CE is the signal to enable Flash chip.

NFC_CE0 and NFC_CE1 is in fact used as the flash chip select pin.

the signals on both pins are same, you can certainly connect PTC17 or PTC18 to your flash chip if there is only one NAND flash on the board.
