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.
