I have an SDRAM (MT48LC8M16A2TG) connected to 5509A and willing to use pin 16, 22 and 25 which are GPIO 8, 10, 11 respectively, as general purpose output pins. Trying all but could not change their state as I can easily do with GPIO7. I will be happy if you will help me. Best regards, Cem VARDAR |
how to use GPIO 8,

hi, Except GPIO0-GPIO7, other GPIO lines are multiplexed with other signal functionalities in C5509A. Refer table 3-6 in the datasheet for details.I dont think you can use GPIO8 if you are using any of the EMIF mode. regards, Dileepan. --- In , ahmetcemvardar@y... wrote: > > I have an SDRAM (MT48LC8M16A2TG) connected to 5509A and willing to use pin 16, 22 and 25 which are GPIO 8, 10, 11 respectively, as general purpose output pins. > > Trying all but could not change their state as I can easily do with GPIO7. > > I will be happy if you will help me. > > Best regards, > > Cem VARDAR |
