of these internal signals reflect the state of low-level MDEU functions, such as data padding, key padding,

etc., and are not important to the user; however the user should be aware that reads of this register,

Reset interrupt. Writing this bit active high causes MDEU interrupts signaling DONE and ERROR to be reset. It

further resets the state of the MDEU interrupt status register.

1 Reset interrupt logic

Module initialization is nearly the same as software reset, except that the MDEU interrupt control register remains

1 Reset most of MDEU

Software reset is functionally equivalent to hardware reset (the RESET signal), but only for the MDEU. All

registers and internal state are returned to their defined reset state.

Writing to the data size register will allow the MDEU to enter auto-start

mode. Therefore, the required context registers must be written prior to

writing the data size.
