Detailed Description

Macros for pin control configuration of Ambiq Apollo4.

The macros follow the following naming convention: <FUNCTION>_P<PIN>.

For example, UART0TX_P60 corresponds to selecting the UART0TX function on pin 60.

#include <zephyr/dt-bindings/pinctrl/ambiq-apollo4-pinctrl.h>
 
&pinctrl {
        uart0_default: uart0_default {
                group1 {
                        pinmux = <UART0TX_P60>;
                };
                group2 {
                        pinmux = <UART0RX_P47>;
                        input-enable;
                };
        };
};
