RESET
FUNCTION
20
BUF2WM1
RW
0
Buffer 2 water mark 1 When this bit is set to 1, the SYSINT.DBINT1 bit
is set to 1 when the corresponding bit in the DBINT0 register is set by
hardware. When set to 0, the corresponding bit in the DBINT0 register
has no effect on the SYSINT.DBINT1 bit.
19
BUF2WM0
RW
0
Buffer 2 water mark 0 When this bit is set to 1, the SYSINT.DBINT1 bit
is set to 1 when the corresponding bit in the DBINT0 register is set by
hardware. When set to 0, the corresponding bit in the DBINT0 register
has no effect on the SYSINT.DBINT1 bit.
18
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
17
BUF2FULL
RW
0
Buffer 2 full When this bit is set to 1, the SYSINT.DBINT1 bit is set to 1
when the corresponding bit in the DBINT0 register is set by hardware.
When set to 0, the corresponding bit in the DBINT0 register has no effect
on the SYSINT.DBINT1 bit.
16
BUF2EMPTY
RW
1
Buffer 2 empty When this bit is set to 1, the SYSINT.DBINT1 bit is set to
1 when the corresponding bit in the DBINT0 register is set by hardware.
When set to 0, the corresponding bit in the DBINT0 register has no effect
on the SYSINT.DBINT1 bit.
15
BUF1CELLCFRM
RW
0
Buffer 1 cell confirm When this bit is set to 1, the SYSINT.DBINT0 bit is
set to 1 when the corresponding bit in the DBINT0 register is set by hard-
ware. When set to 0, the corresponding bit in the DBINT0 register has no
effect on the SYSINT.DBINT0 bit.
14
BUF1TSREL
RW
0
Buffer 1 time stamp release When this bit is set to 1, the
SYSINT.DBINT0 bit is set to 1 when the corresponding bit in the DBINT0
register is set by hardware. When set to 0, the corresponding bit in the
DBINT0 register has no effect on the SYSINT.DBINT0 bit.
13
BUF1AGED
RW
0
Buffer 1 time stamp expired When this bit is set to 1, the
SYSINT.DBINT0 bit is set to 1 when the corresponding bit in the DBINT0
register is set by hardware. When set to 0, the corresponding bit in the
DBINT0 register has no effect on the SYSINT.DBINT0 bit.
12
BUF1WM1
RW
0
Buffer 1 water mark 1 When this bit is set to 1, the SYSINT.DBINT0 bit
is set to 1 when the corresponding bit in the DBINT0 register is set by
hardware. When set to 0, the corresponding bit in the DBINT0 register
has no effect on the SYSINT.DBINT0 bit.
11
BUF1WM0
RW
0
Buffer 1 water mark 0 When this bit is set to 1, the SYSINT.DBINT0 bit
is set to 1 when the corresponding bit in the DBINT0 register is set by
hardware. When set to 0, the corresponding bit in the DBINT0 register
has no effect on the SYSINT.DBINT0 bit.
10
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
9
BUF1FULL
RW
0
Buffer 1 full When this bit is set to 1, the SYSINT.DBINT0 bit is set to 1
when the corresponding bit in the DBINT0 register is set by hardware.
When set to 0, the corresponding bit in the DBINT0 register has no effect
on the SYSINT.DBINT0 bit.
