Description
Least Significant Bit for HDTFThresh detection threshold.
Combines with HDTFThresh bits in register 04h.
Least Significant Bit for SDTFThresh detection threshold.
Combines with SDTFThresh bits in register 05h.
Reserved as 000. Always write 000 to these bits.
Direction of TFN that affects FAULT pin (when not masked).
0: TFN=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFN=0 will cause FAULT to be 0 (when the condition is
not masked off).
Direction of TFP that affects FAULT pin (when not masked).
0: TFP=1 will cause FAULT to be 0 (when the condition is
not masked off).
1: TFP=0 will cause FAULT to be 0 (when the condition is
not masked off).
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).
Sets the Termination Fault threshold for SDO, when SD is
set to HD rates (0). Combines with HDTFThreshLSB in
register 03h (default for combined value is 1000).
SDO output amplitude in roughly 5 mV steps.
