Function esp_idf_svc::hal::sys::esp_efuse_write_field_bit

pub unsafe extern "C" fn esp_efuse_write_field_bit(
    field: *mut *const esp_efuse_desc_t,
) -> i32

@brief Write a single bit eFuse field to 1

For use with eFuse fields that are a single bit. This function will write the bit to value 1 if it is not already set, or does nothing if the bit is already set.

This is equivalent to calling esp_efuse_write_field_cnt() with the cnt parameter equal to 1, except that it will return ESP_OK if the field is already set to 1.

@param[in] field Pointer to the structure describing the efuse field.

@return

• ESP_OK: The operation was successfully completed, or the bit was already set to value 1.
• ESP_ERR_INVALID_ARG: Error in the passed arugments, including if the efuse field is not 1 bit wide.
