Ensure that RNG_CTRL.REQ and RNG_CTRL.GRANT are cleared to ‘0’.
Set RNG_CTRL.REQ to ‘1’. If an interrupt is desired also set RNG_CTRL.IRQ_EN to ‘1’.
RNG_CTRL.IRQ_CLR must be cleared to ‘0’.
Wait for RNG_CTRL.GRANT to be set ‘1’, either by polling or receiving an IRQ (if
RNG_CTRL.IRQ_EN was set).
Clear
RNG_CTRL.GRANT bit as well as the contents of RNG_DATA.
If active, the interrupt can be cleared by writing RNG_CTRL.IRQ_CLR to ‘1’.
