Notes:
• Because the Frame Buffer is shared between TX and RX, the frame data are
• If the SRAM access mode is used to upload received frames, the Frame Buffer
• It is not possible to transmit received frames without a Frame Buffer read and write
• Frame Buffer access violations are not indicated by a TXR_UR interrupt when using
The AT86RF230 can be identified by four registers. One register contains an unique
part number and one register the corresponding version number. Additional two
registers contain the JEDEC manufacturer ID.
