RX_BUFFER
RX Frame Data Buffer – included in swinging set
Register map register file 0x11 is the receive data buffer. The data from the received frame is available in
the received buffer. Assuming successful reception of a good frame, the full length of received data (as
reported by the RXFLEN and RXFLE fields of Register file: 0x10 – RX Frame Information Register), will be
available in the RX_BUFFER beginning at offset 0. Note since the reported length includes the FCS the host
system will probably choose not to read these final two octets.
Write operations to the RX_BUFFER are NOT supported; a write operation to the RX_BUFFER will corrupt
the buffer contents.
Register file: 0x11 – RX Frame Buffer is part of the RX double-buffered swinging-set. See section 4.3 –
Double Receive Buffer for more details.
