SW_RESET, or module initialization, which performs proper initialization of the S-box. To determine

when this is complete, poll the RESET_DONE bit in the AFEU status register.

This status register, shown in

The AFEU status register is read-only. Writing to this location results in an address error being reflected

in the AFEU interrupt status register.

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

further resets the state of the AFEU interrupt status register.

0 Do not reset

1 Reset interrupt logic

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

0 Do not reset

1 Reset most of AFEU

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

and internal states are returned to their defined reset state. On negation of SW_RESET, the AFEU enters a

routine to perform proper initialization of the S-box.
