Bits Field
Default Description
7 HDTFThresh0LSB 0 Least Significant Bit for HDTFThresh0 detection threshold.
Combines with HDTFThresh0 bits in register 04h.
6 SDTFThresh0LSB 0 Least Significant Bit for SDTFThresh0 detection threshold.
Combines with SDTFThresh0 bits in register 05h.
5 RSVD
0 Reserved as 0. Always write 0 to this bit.
4 DTFN1
0 Direction of TFN1 that affects FAULT pin (when not masked).
0: TFN1=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFN1=0 will cause FAULT to be 0 (when the condition is
not masked off).
3 DTFP1
0 Direction of TFP1 that affects FAULT pin (when not masked).
0: TFP1=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFP1=0 will cause FAULT to be 0 (when the condition is
not masked off).
2 DTFN0
0 Direction of TFN0 that affects FAULT pin (when not masked).
0: TFN0=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFN0=0 will cause FAULT to be 0 (when the condition is
not masked off).
1 DTFP0
0 Direction of TFP0 that affects FAULT pin (when not masked).
0: TFP0=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFP0=0 will cause FAULT to be 0 (when the condition is
not masked off).
0 DLOS
0 Direction of LOS that affects FAULT pin (when not masked).
0: LOS=0 will cause FAULT to be 0 (when the condition is not
masked off).
1: LOS=1 will cause FAULT to be 0 (when the condition is not
masked off).
7:5 HDTFThresh0
100 Sets the Termination Fault threshold for SDO0, when SD is
set to HD rates (0). Combines with HDTFThresh0LSB in
register 03h (default for combined value is 1000).
4:0 AMP0
10000 SDO0 output amplitude in roughly 5 mV steps.
