STM32_MODER_INPUT_MODE

#define STM32_MODER_INPUT_MODE   (0x0 << STM32_MODER_SHIFT)

PIN configuration bitfield.

Pin configuration is coded with the following fields [03:00] Alternate Functions [05:04] GPIO Mode [ 06] GPIO Output type [08:07] GPIO Speed [10:09] GPIO PUPD config [ 11] GPIO Output data

These fields are only used when pinctrl with compatible "st,stm32n6-pinctrl" is in use: [15:12] I/O delay length [ 16] I/O delay direction [18:17] I/O retime edge [ 19] I/O retime enable

NOTE: the values for these fields are not defined in this file because they depend on hardware definitions. The values can be found in soc/st/stm32/common/pinctrl_soc.h instead.
