New Data[0:31]
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 CPU 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
