CYW20819 GPIO can be set to various function like UART, I2C, SPI, ... with wiced_hal_gpio_select_function();
I'd like to know pull-up or pull down configuration of PUART input lines.
Is there some documentation that describe pull-up or pull down configuration by wiced_hal_gpio_select_function()?
Is it possible to change pull-up or pull down configuration for PUART?

Hi ToKo_4602001 ,
In general its not recommended to have any pull up / down configuration for UART pins.
If you want like - some GPIOs to be used as puart for some time and then make the pins pull up/ down for some time means you can use wiced_hal_gpio_select_function to switch between PUART and GPIO functionality. And use wiced_hal_gpio_configure_pin API to set pull up/ down
Thank you for your quick reply.
I want to know the pull configuration for P_UART with wiced_hal_gpio_select_function().
According to datasheet H_UART lines are set to the following configuration.
H_UART_CTS: I, PU
H_UART_RTS: O, PU
H_UART_RXD: I (No-pull)
H_UART_TXD: O, PU
In a similar way, I' like to know P_UART confuguration.
