0x150 DBINT0EN Data Buffer Interrupt 0 Enables (Continued)
BIT
NAME
TYPE
RESET
FUNCTION
8
BUF1EMPTY
RW
0
Buffer 1 empty 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.
7
BUF0CELLCFRM
RW
0
Buffer 0 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
hardware. When set to 0, the corresponding bit in the DBINT0 register
has no effect on the SYSINT.DBINT0 bit.
6
BUF0TSREL
RW
0
Buffer 0 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.
5
BUF0AGED
RW
0
Buffer 0 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.
4
BUF0WM1
RW
0
Buffer 0 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.
3
BUF0WM0
RW
0
Buffer 0 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.
2
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
1
BUF0FULL
RW
0
Buffer 0 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.
0
BUF0EMPTY
RW
0
Buffer 0 empty 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.
0x154 DBINT1 – Data Buffer Interrupts 1
BIT
NAME
TYPE
RESET
FUNCTION
31
BUF7CELLCFRM
RCU
0
Buffer 7 cell confirm – This bit is set by hardware to indicate that a
complete logical cell has been confirmed into the associated buffer.
30
BUF7TSREL
RCU
0
Buffer 7 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.
29
BUF7AGED
RCU
0
Buffer 7 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.
28
BUF7WM1
RCU
0
Buffer 7 water mark 1 This bit is set by hardware to indicate that
DBSTAT1.BUF7WM1 has changed its status from 0 to 1.
