DES Cryptographic Data Length (DES_LENGTH)
Indicates the cryptographic data length in bytes for all modes. Once processing is started with this context, this length decrements to zero. Data lengths up to (232 - 1) bytes are allowed. A write to this register triggers the engine to start using this context.
NOTE
A read of this register returns all zeros.
DES_LENGTH is shown in Figure 14-12 and described in Table 14-14.
