Bit
Name
Description
7
DAC_IS
This bit indicates the interrupt status of the waveform amplitude overflow.
0: No waveform amplitude overflow interrupt is generated; or a ‘1’ is written to this bit. (default)
1: Waveform amplitude overflow interrupt is generated and is reported by the INT pin.
6
TJA_IS
This bit indicates the interrupt status of the TJA FIFO overflow or underflow.
0: No TJA FIFO overflow or underflow interrupt is generated; or a ‘1’ is written to this bit. (default)
1: TJA FIFO overflow or underflow interrupt is generated and is reported by the INT pin.
5
RJA_IS
This bit indicates the interrupt status of the RJA FIFO overflow or underflow.
0: No RJA FIFO overflow or underflow interrupt is generated; or a ‘1’ is written to this bit. (default)
1: RJA FIFO overflow or underflow interrupt is generated and is reported by the INT pin.
4
TOC_IS
This bit indicates the interrupt status of the Line Driver TOC.
0: No TOC interrupt is generated; or a ‘1’ is written to this bit. (default)
1: TOC interrupt is generated and is reported by the INT pin. When the TOC_IES bit (b4,
INTES,...) is ‘0’, a transition from ‘0’ to
‘1’ on the TOC_S bit (b4,
STAT0,...) set this bit to ‘1’; when the TOC_IES bit (b4,
INTES,...) is ‘1’, any transition (from ‘0’ to ‘1’ or
from ‘1’ to ‘0’) on the TOC_S bit (b4,
STAT0,...) set this bit to ‘1’.
3
TCKLOS_IS
This bit indicates the interrupt status of the TCLKn missing.
0: No TCLKn missing interrupt is generated; or a ‘1’ is written to this bit. (default)
1: TCLKn missing interrupt is generated and is reported by the INT pin. When the TCKLOS_IES bit (b3,
INTES,...) is ‘0’, a transi-
tion from ‘0’ to ‘1’ on the TCKLOS_S bit (b3,
STAT0,...) set this bit to ‘1’; when the TCKLOS_IES bit (b3,
INTES,...) is ‘1’, any tran-
sition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the TCKLOS_S bit (b3,
STAT0,...) set this bit to ‘1’.
2
TLOS_IS
This bit indicates the interrupt status of TLOS.
0: No TLOS interrupt is generated; or a ‘1’ is written to this bit. (default)
1: TLOS interrupt is generated and is reported by the INT pin. When the TLOS_IES bit (b2,
INTES,...) is ‘0’, a transition from ‘0’
to ‘1’ on the TLOS_S bit (b2,
STAT0,...) set this bit to ‘1’; when the TLOS_IES bit (b2,
INTES,...) is ‘1’, any transition (from ‘0’ to
‘1’ or from ‘1’ to ‘0’) on the TLOS_S bit (b2,
STAT0,...) set this bit to ‘1’.
1
SLOS_IS
This bit indicates the interrupt status of the SLOS.
0: No SLOS interrupt is generated; or a ‘1’ is written to this bit. (default)
1: SLOS interrupt is generated and is reported by the INT pin. When the LOS_IES bit (b1,
INTES,...) is ‘0’, a transition from ‘0’ to
‘1’ on the SLOS_S bit (b1,
STAT0,...) set this bit to ‘1’; when the LOS_IES bit (b1,
INTES,...) is ‘1’, any transition (from ‘0’ to ‘1’ or
from ‘1’ to ‘0’) on the SLOS_S bit (b1,
STAT0,...) set this bit to ‘1’.
0
LLOS_IS
This bit indicates the interrupt status of the LLOS.
0: No LLOS interrupt is generated; or a ‘1’ is written to this bit. (default)
1: LLOS interrupt is generated and is reported by the INT pin. When the LOS_IES bit (b1,
INTES,...) is ‘0’, a transition from ‘0’ to
‘1’ on the LLOS_S bit (b0,
STAT0,...) set this bit to ‘1’; when the LOS_IES bit (b1,
INTES,...) is ‘1’, any transition (from ‘0’ to ‘1’ or
from ‘1’ to ‘0’) on the LLOS_S bit (b0,
STAT0,...) set this bit to ‘1’.
