Description
Off-state output fault diagnostics control bit. Active-high. HIGH:
Off-state fault diagnostics disabled; LOW: Off-state fault
diagnostics enabled
Adjacent-pin diagnostics start control bit. Active-high, returns low
when adjacent-pin diagnostic procedure is concluded.
HIGH: Start adjacent-pin diagnostics or adjacent-pin diagnostics
are ongoing; LOW: Adjacent-pin diagnostics are not running.
Slow slew rate control bit. Active-high. HIGH: Output-current
slew rate is in slow mode. LOW: Output-current slew rate is in
normal mode.
Force error control bit. Active-high. HIGH: ERR output is forced
low. LOW: ERR output is not forced low.
Weak-LED-supply threshold-control bit. Active-high. HIGH: WLS
threshold is set to 3.3-V mode. LOW: WLS threshold is set to 5-
V mode.
