Struct AesEcbRegistersManager 

pub struct AesEcbRegistersManager {
    pub registers: StaticRef<AesEcbRegisters>,
    /* private fields */
}

Wrapper for managing MMIO for the AES ECB peripheral.

Fields

registers: StaticRef<AesEcbRegisters>

MMIO registers for the AES ECB peripheral.

Implementations

impl AesEcbRegistersManager

pub unsafe fn new(regs: StaticRef<AesEcbRegisters>) -> AesEcbRegistersManager

Create a new AES registers manager.

Safety

This controls DMA hardware. As such, it must be unique. This requires:

• This constructor must be called at most once.
• There must not be any other code that accesses the DMA buffer and length registers.

pub fn start_ecb_dma(&self, buf: &'static mut [u8]) -> Result<(), ()>

Start an ECB encryption with DMA.

The buffer must cover the full 48-byte ECB data block: bytes 0–15 = key, bytes 16–31 = plaintext/counter, bytes 32–47 = ciphertext output.

Return

Ok(()) on successfully starting the DMA operation. Err(()) if DMA is already busy.

pub fn finish_ecb_dma(&self) -> Option<&'static mut [u8]>

pub fn dma_pending(&self) -> bool
