Security Engine (SEC) 3.0
Most of the registers described here would not normally be accessed by the host. They are documented
here mainly for debug purposes. In typical operation, the RNGU is used through channel-controlled
access, which means that most reads and writes of RNGU registers are directed by the SEC channels.
Driver software would perform host-controlled register accesses only on a few registers for initial
configuration and error handling.
10.7.8.1
The RNGU Mode Register is a writable location but all mode bits are currently reserved. It is documented
for the sake of consistency with the other EUs. The RNGU mode register is shown in
Offset 0x3_A000
10.7.8.2
The RNGU data size register is used to tell the RNGU to begin generating random data. The actual
contents of the data size register does not affect the operation of the RNGU. After a reset and prior to the
first write of data size, the RNGU builds entropy without pushing data onto the FIFO. Once the data size
register is written, the RNGU begins pushing data onto the FIFO. One dword (64 bits) of data is pushed
onto the FIFO every 112 cycles until the FIFO is full. The RNGU then attempts to keep the FIFO full.
