RESET
FUNCTION
27
BUF7WM0
RCU
0
Buffer 7 water mark 0 This bit is set by hardware to indicate that
DBSTAT1.BUF7WM0 has changed its status from 0 to 1.
26

25
BUF7FULL
RCU
0
Buffer 7 full – When set to 1, indicates that there is no space available
in the current buffer.
24
BUF7EMPTY
RCU
0
Buffer 7 empty – When set to 1, indicates that there is no data in the
current buffer.
23
BUF6CELLCFRM
RCU
0
Buffer 6 cell confirm – This bit is set by hardware to indicate that a
complete logical cell has been confirmed into the associated buffer.
22
BUF6TSREL
RCU
0
Buffer 6 time stamp release – This bit is set by hardware to indicate
that a time-stamped logical cell in the current buffer is ready to be
released, irrespective of buffer direction.
21
BUF6AGED
RCU
0
Buffer 6 time stamp expired – This bit is set by hardware to indicate
that a time-stamped logical cell in the current buffer has been flushed
because its time stamp expired, irrespective of buffer direction.
20
