In the TRM doc (2024-4-18 version), it states in Section 25.5

The address in the following table is relative to the random number generator base address provided in Table
4-3 in Chapter 4 System and Memory.

. The relative address is of the RNG_DATA_REG.

But in that table, there is no entry for RNG. So the absolute address of RNG_DATA_REG is unknown. Is there an answer for this?

Hello @DrRossPhD,

The base address of the ESP32-S3 RNG module is 0x60033000, and the absolute address of RNG_DATA_REG, given its offset of 0x0110, is 0x60033110. We will update our related documentation shortly.

Thank you.
