RESET
FUNCTION
5
BUF4AGED
RCU
0
Buffer 4 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.
4
BUF4WM1
RCU
0
Buffer 4 water mark 1 This bit is set by hardware to indicate that
DBSTAT1.BUF4WM1 has changed its status from 0 to 1.
3
BUF4WM0
RCU
0
Buffer 4 water mark 0 This bit is set by hardware to indicate that
DBSTAT1.BUF4WM0 has changed its status from 0 to 1.
2
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
1
BUF4FULL
RCU
0
Buffer 4 full – When set to 1, indicates that there is no space available
in the current buffer.
0
BUF4EMPTY
RCU
0
Buffer 4 empty – When set to 1, indicates that there is no data in the
current buffer.

FUNCTION
31
BUF7CELLCFRM
RW
0
Buffer 7 cell confirm When this bit is set to 1, the SYSINT.DBINT3 bit
is set to 1 when the corresponding bit in the DBINT1 register is set by
hardware. When set to 0, the corresponding bit in the DBINT1 register
has no effect on the SYSINT.DBINT3 bit.
30
BUF7TSREL
RW
0
Buffer 7 time stamp release When this bit is set to 1, the
SYSINT.DBINT3 bit is set to 1 when the corresponding bit in the
DBINT1 register is set by hardware. When set to 0, the corresponding
bit in the DBINT1 register has no effect on the SYSINT.DBINT3 bit.
29
BUF7AGED
RW
0
Buffer 7 time stamp expired When this bit is set to 1, the
SYSINT.DBINT3 bit is set to 1 when the corresponding bit in the
DBINT1 register is set by hardware. When set to 0, the corresponding
bit in the DBINT1 register has no effect on the SYSINT.DBINT3 bit.
28
BUF7WM1
RW
0
Buffer 7 water mark 1 When this bit is set to 1, the SYSINT.DBINT3
bit is set to 1 when the corresponding bit in the DBINT1 register is set
by hardware. When set to 0, the corresponding bit in the DBINT1 reg-
ister has no effect on the SYSINT.DBINT3 bit.
27
BUF7WM0
RW
0
Buffer 7 water mark 0 When this bit is set to 1, the SYSINT.DBINT3
bit is set to 1 when the corresponding bit in the DBINT1 register is set
by hardware. When set to 0, the corresponding bit in the DBINT0
register has no effect on the SYSINT.DBINT3 bit.
26
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
25
BUF7FULL
RW
0
Buffer 7 full When this bit is set to 1, the SYSINT.DBINT3 bit is set to 1
when the corresponding bit in the DBINT1 register is set by hardware.
When set to 0, the corresponding bit in the DBINT1 register has no
effect on the SYSINT.DBINT3 bit.
24
BUF7EMPTY
RW
0
Buffer 7 empty When this bit is set to 1, the SYSINT.DBINT3 bit is set
to 1 when the corresponding bit in the DBINT1 register is set by hard-
ware. When set to 0, the corresponding bit in the DBINT1 register has
no effect on the SYSINT.DBINT3 bit.
