BUFFULL
Set when the result buffer is full
BUFHALFFULL
Set when the result buffer is half full
BUFDATAV
Set when data is available in the result buffer. Cleared when the buffer is empty.
Reserved
WR
These bits show the next index in the result buffer to be written to. Incremented when LESENSE writes to result buffer
Reserved
RD
These bits show the index of the oldest unread data in the result buffer. Incremented on read from BUFDATA.
