Struct nrf52840_hal::uicr::Uicr

pub struct Uicr(_);

Interface to a UICR instance.

This is a very basic interface that comes with the following limitations:

• Only customer registers are usable for storing and loading of data
• Erase must be performed in order to write bits with value 1 over 0

Implementations

impl Uicr

pub fn new(uicr: UICR) -> Uicr

Construct a new Uicr from pac::UICR.

pub fn free(self) -> UICR

Release the pac::UICR instance back.

pub fn erase(&mut self, nvmc: &mut NVMC)

Erase the UICR registers.

UICR registers can only be set to 0 bits, additional overrides back to 1 can only be performed by erasing the UICR registers.

• Sets all registers to 0xFFFF_FFFFu32

pub fn store_customer(&mut self, nvmc: &mut NVMC, offset: usize, values: &[u32])

Store a slice of &[u32] values to the customer registers with given offset.

• offset + slice length must be less than 32
• initial value after erase is 0xFFFF_FFFFu32
• UICR registers can only be set to 0 bits, additional overrides back to 1 can only be performed by erasing the UICR registers

pub fn load_customer(
    &mut self,
    offset: usize,
    values: &'a mut [u32]
) -> &'a [u32]

Load a slice of &[u32] values to the customer registers from given offset.

• offset + slice length must be less than 32
• returns the loaded slice
