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 1001).
SDO output amplitude in roughly 5 mV steps.
