hi,experts

   we want to modify our hardware board from original LPDDR4 to DDR4 or DDR3L , we checked the design guide , we found that DDR_SEL(attatched) is used to config the voltage of DDR interface , but i can not find this pin in the pin layout. could you please help us to find where is the DDR_SEL pin or how to do when we want to modify the hardware from LPDDR4 to DDR4 or DDR3L?

thanks.
