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 is only valid on an nrf5x-based MCU. This must only be called once as having multiple interfaces to DMA registers is not safe. This must be the only way the AES DMA registers are controlled.

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.
