[RT1050] For winbond W9825G6KH-6I, 166MHz, What is recommend value for pin mux ?

[bryan_hong]

Dear nxp

I have attached winbond W9825G6KH-6I datasheet. 

I want to know recommend value for PAD setting especially SW_MUX_CTL_PAD_GPIO_EMC_26 SW MUX Control Register when SDRAM CLK set to 163MHz.

Below is for now.

<pin peripheral="SEMC" signal="semc_clk" pin_num="B3" pin_signal="GPIO_EMC_26">

                     <pin_features>

                        <pin_feature name="software_input_on" value="Disable"/>

                        <pin_feature name="hysteresis_enable" value="Disable"/>

                        <pin_feature name="pull_up_down_config" value="Pull_Down_100K_Ohm"/>

                       <pin_feature name="pull_keeper_select" value="Keeper"/>

                        <pin_feature name="pull_keeper_enable" value="Enable"/>

                        <pin_feature name="open_drain" value="Disable"/>

                        <pin_feature name="speed" value="MHZ_100"/>

                        <pin_feature name="drive_strength" value="R0_6"/>

                        <pin_feature name="slew_rate" value="Slow"/>

                     </pin_features>

                  </pin>

thanks

Dear Jing

How to get the SEMC demo? Is it source code foe RT1050?

Hi @bryan_hong ,

Normally we set it to 

hysteresis_enable: Enable, speed: MHZ_200, drive_strength: R0_7, slew_rate: Fast

You can refer to the SEMC demo. The pin parameter is set in pin_mux.c
