Random Number Generator
Overview
Register Description
The AT86RF231 incorporates a 2-bit truly random number generator by observation of noise.
This random number can be used to:
The random number is updated every t
values are stored in register bits RND_VALUE (register 0x06, PHY_RSSI).
Register 0x06 (PHY_RSSI):
Register 0x06 (PHY_RSSI) is a multi purpose register to indicate FCS validity, to provide ran-
dom numbers and an RSSI value.
• Bit 7 - RX_CRC_VALID
Refer to register description in
• Bit [6:5] - RND_VALUE
The 2-bit random value can be retrieved by reading register bits RND_VALUE. Note that the
radio transceiver shall be in Basic Operating Mode receive state. The values are updated each
t
• Bit [4:0] - RSSI
Refer to register description in

= 1 µs.
Ensure that register bit RX_PDT_DIS (register 0x15, RX_SYN) is set to 0 at least 1 µs before
reading a random value.
