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> ...
For UART, The RXD pin will be configured as GPIO, digital mode enabled, pull-up enabled for auto baud function, and keep TXD pin to default state. When Auto baud is done, then both RXD and TXD pin will be configured to UART function, digital mode enabled, faste...
