A software reset of the module can be done by writing 1 to the TRNG:SWRESET.RESET register. When a software reset completes the TRNG:SWRESET.RESET register is automatically reset to 0. By polling the TRNG:SWRESET.RESET register for 0 the software can ensure that the reset is completed, the software reset must be completed before doing any TRNG operations.
