HSEM driver

Implementations

impl<T: Instance> HardwareSemaphore<T>

pub fn new<'d>( _peripheral: Peri<'d, T>, _irq: impl Binding<T::Interrupt, HardwareSemaphoreInterruptHandler<T>> + 'd, ) -> Self

Creates a new HardwareSemaphore instance.

pub const fn channel_for<'a>( &'a mut self, number: u8, ) -> HardwareSemaphoreChannel<'a, T>

Get a single channel, and keep the global struct

pub const fn split<'a>(self) -> [HardwareSemaphoreChannel<'a, T>; 6]

Split the global struct into channels

If using low-power mode, channels 3 and 4 will not be returned

pub fn unlock_all(&mut self, key: u16, core_id: u8)

Unlocks all semaphores. All semaphores locked by a COREID can be unlocked at once by using the HSEM_CR register. Write COREID and correct KEY value in HSEM_CR. All locked semaphores with a matching COREID are unlocked, and may generate an interrupt when enabled.

pub fn set_clear_key(&mut self, key: u16)

Sets the clear (unlock) key

pub fn get_clear_key(&mut self) -> u16

Gets the clear (unlock) key
