0x158 DBEINTEN – Data Buffer Interrupt 1 Enables (Continued)
BIT
NAME
TYPE
RESET
FUNCTION
12
BUF5WM1
RW
0
Buffer 5 water mark 1 When this bit is set to 1, the SYSINT.DBINT2
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.DBINT2 bit.
11
BUF5WM0
RW
0
Buffer 5 water mark 0 When this bit is set to 1, the SYSINT.DBINT2
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.DBINT2 bit.
10
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
9
BUF5FULL
RW
0
Buffer 5 full When this bit is set to 1, the SYSINT.DBINT2 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.DBINT2 bit.
8
BUF5EMPTY
RW
0
Buffer 5 empty When this bit is set to 1, the SYSINT.DBINT2 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.DBINT2 bit.
7
BUF4CELLCFRM
RW
0
Buffer 4 cell confirm When this bit is set to 1, the SYSINT.DBINT2 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.DBINT2 bit.
6
BUF4TSREL
RW
0
Buffer 4 time stamp release When this bit is set to 1, the
SYSINT.DBINT2 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.DBINT2 bit.
5
BUF4AGED
RW
0
Buffer 4 time stamp expired When this bit is set to 1, the
SYSINT.DBINT2 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.DBINT2 bit.
4
BUF4WM1
RW
0
Buffer 4 water mark 1 When this bit is set to 1, the SYSINT.DBINT2
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.DBINT2 bit.
3
BUF4WM0
RW
0
Buffer 4 water mark 0 When this bit is set to 1, the SYSINT.DBINT2
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.DBINT2 bit.
2
RSVD
R0
0
Reserved – A write to this location has no effect. A read returns 0.
1
BUF4FULL
RW
0
Buffer 4 full When this bit is set to 1, the SYSINT.DBINT2 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.DBINT2 bit.
0
BUF4EMPTY
RW
0
Buffer 4 empty When this bit is set to 1, the SYSINT.DBINT2 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.DBINT2 bit.
