Random Number Generator (RNG)
After this, a random 32-bit word is pushed to the FIFO every 256 cycles. If the FIFO is full, then
no push will occur.
In this way the FIFO will be kept as close to full as possible. The fields in the RNGCR are defined
in
29.2.2 RNG Status Register (RNGSR)

Clear interrupt. Writing a one to this bit clears the error interrupt and RNGSR[EI].
0 Do not clear error interrupt.
1 Clear error interrupt.
Interrupt mask.
0 Error interrupt is enabled.
1 Error interrupt is masked.
High assurance. Notifies core when FIFO underflow has occurred (FIFO is read while
empty). Enables the Security Violation bit in the RNGSR. Bit is sticky and can only be
cleared by hardware reset.
0 Disable security violation notification.
1 Enable security violation notification.
Go bit. Starts/stops random data from being generated. Bit is sticky and can only be
cleared by hardware reset.
0 FIFO is not loaded with random data.
1 FIFO will be loaded with random data.
