9.2 Random Number Generator
9.2.1 Overview
9.2.2 Register Description

Register 0x94 (AES_CTRL_MIRROR):
Register 0x94 is a mirrored version of register 0x83 (AES_CTRL); for details, refer to
register 0x83 (AES_CTRL).
Table 9-9. Register 0x94 (AES_CTRL_MIRROR)
This register could be used to start a security operation within a single SRAM access by
appending it to the data stream and setting register bit AES_REQUEST = 1.
The AT86RF212 provides a 2-bit random number generator. This random number can
be used to
• generate random seeds for CSMA-CA algorithm, see section 5.2
• generate random values for AES key generation, see section 9.1
Random numbers are stored in register bits RND_VALUE (register 0x06, PHY_RSSI).
The random number is updated at every read access in Basic Operating Mode receive
states (RX_ON, BUSY_RX). The Random Number Generator does not work if the
preamble detector is disabled (RX_PDT_DIS = 1, refer to section 7.2.3).
Register 0x06 (PHY_RSSI):
Register 0x06 (PHY_RSSI) is a multi purpose register to indicate FCS validity, to
provide random numbers, and an RSSI value.
