Default Description
0010111 Device ID. Writing this register will force the RSTO pin high.
Further accesses to the device must use this 7-bit address.
0 Reserved as 0. Always write 0 to this bit.
000 Reserved
0 Termination Fault for SDI1.
0: No Termination Fault Detected
1: Termination Fault Detected
0 Termination Fault for SDI1.
0: No Termination Fault Detected
1: Termination Fault Detected
0 Termination Fault for SDI0.
0: No Termination Fault Detected
1: Termination Fault Detected
0 Termination Fault for SDI0.
0: No Termination Fault Detected
1: Termination Fault Detected
0 Loss Of Signal (LOS) detect at input.
0: No Signal Detected
1: Signal Detected
0 SD Rate select bit. If the SD/HD pin is set to V_CC, it overrides
this bit. With the SD/HD pin set to ground, this pin selects the
output edge rate as follows:
0: HD edge rate
1: SD edge rate
0 Power Down for SDO1 output stage. If the ENABLE pin is set
to ground, it overrides this bit. With the ENABLE pin set to
V_CC, PD1 functions as follows:
0: SDO1 active
1: SDO1 powered down
0 Power Down for SDO0 output stage. If the ENABLE pin is set
to ground, it overrides this bit. With the ENABLE pin set to
V_CC, PD0 functions as follows:
0: SDO0 active
1: SDO0 powered down
0 Mask TFN1 from affecting FAULT pin.
0: TFN1=1 will cause FAULT to be 0.
1: TFN1=1 will not affect FAULT; the condition is masked off.
0 Mask TFP1 from affecting FAULT pin.
0: TFP1=1 will cause FAULT to be 0.
1: TFP1=1 will not affect FAULT; the condition is masked off.
0 Mask TFN0 from affecting FAULT pin.
0: TFN0=1 will cause FAULT to be 0.
1: TFN0=1 will not affect FAULT; the condition is masked off.
0 Mask TFP0 from affecting FAULT pin.
0: TFP0=1 will cause FAULT to be 0.
1: TFP0=1 will not affect FAULT; the condition is masked off.
0 Mask LOS from affecting FAULT pin.
0: LOS=0 will cause FAULT to be 0.
1: LOS=0 will not affect FAULT; the condition is masked off.
