• OPMOD: Operation Mode
• LOD: Last Output Data Mode
0 = No effect.
After each end of encryption/decryption, the output data is available either on the output data registers (Manual and Auto
modes), or at the address specified in the receive buffer pointer (PDC mode).
In Manual and Auto modes, the DATRDY flag is cleared when at least one of the Output Data registers is read.
1 = The DATRDY flag is cleared when at least one of the Input Data Registers is written.
No more Output Data Register reads is necessary between consecutive encryptions/decryptions (see
Mode” on page
Warning: In PDC mode, reading
unpredictable results.
• CFBS: Cipher Feedback Data Size
• CKEY: Countermeasure Key
This field should be written with the value 0xE to allow CTYPE field changes.
If the field is written with a different value, changes made through the CTYPE field will not be taken into account.
