Struct Qmi

pub struct Qmi { /* private fields */ }

QSPI Memory Interface. Provides a memory-mapped interface to up to two SPI/DSPI/QSPI flash or PSRAM devices. Also provides a serial interface for programming and configuration of the external device.

Implementations

impl Qmi

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

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

pub const fn direct_csr(self) -> Reg<DirectCsr, RW>

Control and status for direct serial mode Direct serial mode allows the processor to send and receive raw serial frames, for programming, configuration and control of the external memory devices. Only SPI mode 0 (CPOL=0 CPHA=0) is supported.

pub const fn direct_tx(self) -> Reg<DirectTx, RW>

Transmit FIFO for direct mode

pub const fn direct_rx(self) -> Reg<DirectRx, RW>

Receive FIFO for direct mode

pub const fn mem(self, n: usize) -> Mem

pub const fn atrans(self, n: usize) -> Reg<Atrans, RW>

Configure address translation for XIP virtual addresses 0x000000 through 0x3fffff (a 4 MiB window starting at +0 MiB). Address translation allows a program image to be executed in place at multiple physical flash addresses (for example, a double-buffered flash image for over-the-air updates), without the overhead of position-independent code. At reset, the address translation registers are initialised to an identity mapping, so that they can be ignored if address translation is not required. Note that the XIP cache is fully virtually addressed, so a cache flush is required after changing the address translation.

Trait Implementations

impl Clone for Qmi

fn clone(&self) -> Qmi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for Qmi

fn eq(&self, other: &Qmi) -> 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.
