Struct Sio

pub struct Sio { /* private fields */ }

Single-cycle IO block Provides core-local and inter-core hardware for the two processors, with single-cycle access.

Implementations

impl Sio

pub const unsafe fn from_ptr(ptr: *mut ()) -> Self

pub const fn as_ptr(&self) -> *mut ()

pub const fn cpuid(self) -> Reg<u32, RW>

Processor core identifier

pub const fn gpio_in(self, n: usize) -> Reg<u32, RW>

Input value for GPIO pins

pub const fn gpio_out(self, n: usize) -> Gpio

pub const fn gpio_oe(self, n: usize) -> Gpio

pub const fn fifo(self) -> Fifo

pub const fn spinlock_st(self) -> Reg<u32, RW>

Spinlock state A bitmap containing the state of all 32 spinlocks (1=locked). Mainly intended for debugging.

pub const fn div(self) -> Div

pub const fn interp(self, n: usize) -> Interp

pub const fn spinlock(self, n: usize) -> Reg<u32, RW>

Reading from a spinlock address will: - Return 0 if lock is already locked - Otherwise return nonzero, and simultaneously claim the lock Writing (any value) releases the lock. If core 0 and core 1 attempt to claim the same lock simultaneously, core 0 wins. The value returned on success is 0x1 << lock number.

Trait Implementations

impl Clone for Sio

fn clone(&self) -> Sio

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for Sio

fn eq(&self, other: &Sio) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
