Change Pin Assignment Setting From External Bus to Peripheral Function

Last Updated:07/04/2018


When running SDRAM, how can I use external bus pins not connected to SDRAM for peripheral functions? 


The external bus pins not connected to SDRAM can be used for peripheral functions by setting a multi-function pin controller (MPC) .
Please refer to the MPC external bus interface setting in the User’s Manual for details. Also, for those pins with the MPC register or external bus interface control register setting section filled with "-" or blank will be  forcibly switched to the function described in the  output signal name or signal name.
