Struct mnemos_d1_core::clint::Clint

pub struct Clint {
    clint: CLINT,
}

Core Local Interruptor (ClINT) interface.

The implementation in the (single) C906 core of the D1 provides timer functionalities that can be accessed from machine and supervisor mode.

Fields

clint: CLINT

Implementations

impl Clint

pub fn new(clint: CLINT) -> Self

Create a new Clint from the CLINT peripheral

pub fn release(self) -> CLINT

Release the underlying CLINT peripheral

pub unsafe fn summon() -> Self

Summon the clint peripheral

Safety

This is intended for use in interrupt context. Care should be taken not to have multiple instances live at the same time that may race or cause other UB issues

pub(crate) fn spin_delay_us(delay_us: usize)

Spin until delay_us microseconds have elapsed (as determined by Self::get_mtime).

pub fn get_mtime() -> usize

Get the (machine) time value.

pub fn set_mtimecmp(&mut self, cmp: usize)

Set the machine time comparator.

When mtime >= this value, a (machine) interrupt will be generated (if configured properly).

pub fn reset_mtimecmp(&mut self)

Reset the machine time comparator to its default value.
