| 31:0 | ND31 to ND0 | R/W | 0 | The register holds the New Data flags of Rx Buffers 0 to 31. The flags are set when the respective Rx Buffer has been updated from a received frame. The flags remain set until the Host clears them. A flag is cleared by writing a ’1’ to the corresponding bit position. Writing a ’0’ has no effect. A hard reset will clear the register.
0 - Rx Buffer not updated 1 - Rx Buffer updated from new message |
