RNG status register. If corresponding RNG_IMR bit is unmasked, an interrupt will be generated.
| EHR_VALID | 1’b1 indicates that 192 bits have been collected in the RNG, and are ready to be read. |
| AUTOCORR_ERR | 1’b1 indicates Autocorrelation test failed four times in a row. When set, RNG cease from functioning until next reset. |
| CRNGT_ERR | 1’b1 indicates CRNGT in the RNG test failed. Failure occurs when two consecutive blocks of 16 collected bits are equal. |
