Auto Mode
PDC Mode
Table 37-1.
Note:
The Auto Mode is similar to Manual Mode, except that, as soon as the correct number of Input
Data registers is written, processing is automatically started without any action in the control
register.
The Peripheral Data Controller (PDC) can be used in association with the TDES to perform an
encryption/decryption of a buffer without any action by the software during processing.
In this starting mode, the type of the data transfer (byte, half-word or word) depends on the oper-
ation mode as per
Table 37-2.
The sequence is as follows:
Note:
• Set the START bit in the TDES Control register TDES_CR to begin the encryption or the
• When the processing completes, the bit DATRDY in the TDES Interrupt Status Register
• When the software reads one of the Output Data Registers (TDES_ODATAxR), the DATRDY
• Write the 64-bit key(s) in the different Key Word Registers (TDES_KEYxWxR), depending on
• Write the initialization vector (or counter) in the Initialization Vector Registers (TDES_IVxR).

TDES_IER, the interrupt line of the TDES is activated.

CFB 16-bit
In 32-, 16- and 8-bit CFB mode, writing to TDES_IDATA2R register is not allowed and may lead to
errors in processing.
The Initialization Vector Registers concern all modes except ECB.
