#[repr(transparent)]pub struct Atrans(pub u32);
Expand description
Configure address translation for XIP virtual addresses 0x1000000 through 0x13fffff (a 4 MiB window starting at +16 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.

Implementations§
source§impl Atrans
impl Atrans
sourcepub const fn base(&self) -> u16
pub const fn base(&self) -> u16
Physical address base for this virtual address range, in units of 4 kiB (one flash sector). Taking a 24-bit virtual address, firstly bits 23:22 (the two MSBs) are masked to zero, and then BASE is added to bits 23:12 (the upper 12 bits) to form the physical address. Translation wraps on a 16 MiB boundary.
sourcepub fn set_base(&mut self, val: u16)
pub fn set_base(&mut self, val: u16)
Physical address base for this virtual address range, in units of 4 kiB (one flash sector). Taking a 24-bit virtual address, firstly bits 23:22 (the two MSBs) are masked to zero, and then BASE is added to bits 23:12 (the upper 12 bits) to form the physical address. Translation wraps on a 16 MiB boundary.
