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

in the RNGU interrupt status register.

Reset Interrupt. Writing this bit active high causes RNGU interrupts signaling done and

error to be reset. It further resets the state of the RNGU interrupt status register.

1 Reset interrupt logic

Module Initialization. This reset value performs enough of a reset to prepare the RNGU for

another request, without forcing the internal control machines and the output FIFO to be

reset, thereby invalidating stored random numbers or requiring reinvocation of a warm-up

period. Module initialization is nearly the same as software reset, except that the interrupt

mask register remains unchanged.

1 Reset most of RNGU

Software reset is functionally equivalent to hardware reset (the RESET# pin), but only for

the RNGU. All registers and internal state are returned to their defined reset state.
