Trait Implementations

impl Readable for GPIO21_SPEC

read() method returns gpio21::R reader structure

type Reader = R

Result from a call to read and argument to modify.

impl RegisterSpec for GPIO21_SPEC

type Ux = u32

Raw register type (u8, u16, u32, …).

impl Resettable for GPIO21_SPEC

reset() method sets GPIO21 to value 0

const RESET_VALUE: <GPIO21_SPEC as RegisterSpec>::Ux = {transmute(0x00000000): <esp_hal_common::esp32::io_mux::gpio21::GPIO21_SPEC as esp_hal_common::esp32::generic::RegisterSpec>::Ux}

Reset value of the register.

fn reset_value() -> Self::Ux

Reset value of the register.

impl Writable for GPIO21_SPEC

write(|w| ..) method takes gpio21::W writer structure

type Writer = W

Writer type argument to write, et al.

const ZERO_TO_MODIFY_FIELDS_BITMAP: <GPIO21_SPEC as RegisterSpec>::Ux = {transmute(0x00000000): <esp_hal_common::esp32::io_mux::gpio21::GPIO21_SPEC as esp_hal_common::esp32::generic::RegisterSpec>::Ux}

Specifies the register bits that are not changed if you pass 1 and are changed if you pass 0

const ONE_TO_MODIFY_FIELDS_BITMAP: <GPIO21_SPEC as RegisterSpec>::Ux = {transmute(0x00000000): <esp_hal_common::esp32::io_mux::gpio21::GPIO21_SPEC as esp_hal_common::esp32::generic::RegisterSpec>::Ux}

Specifies the register bits that are not changed if you pass 0 and are changed if you pass 1
