Value read from the register

impl R

pub fn bits(&self) -> u32
[src]
Value of the register as raw bits
pub fn aes_iv(&self) -> AES_IVR
[src]
Bits 0:31 - 31:0] AES_IV[31:0] Initialization vector Used for regular non-ECB modes (CBC/CTR): -[127:0] - AES_IV - For regular AES operations (CBC and CTR) these registers must be written with a new 128-bit IV. After an operation, these registers contain the latest 128-bit result IV, generated by the EIP-120t. If CTR mode is selected, this value is incremented with 0x1: After first use - When a new data block is submitted to the engine For GCM: -[127:0] - AES_IV - For GCM operations, these registers must be written with a new 128-bit IV. After an operation, these registers contain the updated 128-bit result IV, generated by the EIP-120t. Note that bits [127:96] of the IV represent the initial counter value (which is 1 for GCM) and must therefore be initialized to 0x01000000. This value is incremented with 0x1: After first use - When a new data block is submitted to the engine. For CCM: -[127:0] - A0: For CCM this field must be written with value A0, this value is the concatenation of: A0-flags (5-bits of 0 and 3-bits 'L'), Nonce and counter value. 'L' must be a copy from the 'L' value of the AES_CTRL register. This 'L' indicates the width of the Nonce and counter. The loaded counter must be initialized to 0. The total width of A0 is 128-bit. For CBC-MAC: -[127:0] - Zeroes - For CBC-MAC this register must be written with 0s at the start of each operation. After an operation, these registers contain the 128-bit TAG output, generated by the EIP-120t.
