Implementations§

Source§

impl SPI3

Source

pub const PTR: *const RegisterBlock = {0x40003c00 as *const stm32f4_staging::stm32f429::spi1::RegisterBlock}

Pointer to the register block

Source

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

Source

pub unsafe fn steal() -> SPI3

Steal an instance of this peripheral

§Safety

Ensure that the new instance of the peripheral cannot be used in a way that may race with any existing instances, for example by only accessing read-only or write-only registers, or by consuming the original peripheral and using critical sections to coordinate access between multiple new instances.

Additionally, other software such as HALs may rely on only one peripheral instance existing to ensure memory safety; ensure no stolen instances are passed to such software.
