No Operation Command
Sending these two commands perform no operation. The device outputs will remain in previous state.
FAULT OPERATION
sent to the 33800 and a 16-bit status word is received from
the 33800.

Reset Fault
SO Pin reports short-to-battery/supply or over-current condition.
Not reported on GDX and OUTX outputs. Reported on CCD1 and CCD2 outputs
SO Pin reports output “OFF” open load condition.
Total device shutdown at V
recovery all outputs assume previous state or OFF based on the over-voltage bit in the Shutdown / Retry
Control register.
OUTX & CCDX outputs will remain in current limit until t
CCDX outputs will remain in current limit until TLim is reached.
