Struct Ocotp 

pub struct Ocotp { /* private fields */ }

The OCOTP driver.

Implementations

impl Ocotp

pub fn new(ocotp: OCOTP) -> Self

Construct the driver interface, given the peripheral instance.

pub fn blocking_fuse_read( &mut self, fuse_address: FuseAddress, ) -> Result<u32, Error>

Read a fuse, blocking indefinitely until it returns a value.

This simply spins on the future returned by spin_fuse_read. The approach does not give you a way to specify any timeout. Use only when you’re confident the fuse read will complete.

pub fn blocking_fuse_write( &mut self, fuse_address: FuseAddress, fuse_value: u32, ) -> Result<(), Error>

Write a fuse, blocking indefinitely until it completes.

This simply spins on the future returned by spin_fuse_write. The approach does not give you a way to control a timeout. Use only when you’re confident the write will complete.

pub async fn spin_fuse_read( &mut self, fuse_address: FuseAddress, ) -> Result<u32, Error>

Returns a spinning state machine that reads a fuse value.

The returned task does not consult a waker! You’re expected to spin the CPU on poll() until it returns a value.

The future is not cancel safe. There is no way to cancel an in-flight fuse read. Therefore, errors from prior, incomplete reads may be returned in a subsequent access.

You may compose your own timeouts by using another spinning task, and selecting the winner of the timeout / read.

pub async fn spin_fuse_write( &mut self, fuse_address: FuseAddress, fuse_value: u32, ) -> Result<(), Error>

Returns a spinning state machine that writes a fuse value.

The returned task does not consult a waker! You’re expected to spin the CPU on poll() until it returns a value.

The future is not cancel safe. There is no way to cancel an in-flight fuse write. Therefore, errors from prior, incomplete writes may be returned in a subsequent access.
