M68MPB333UM/D
NOTE
Verify that all socketed parts are seated in their sockets.
CAUTION
Depending on your application, it may be necessary to cut the W2
wiring trace short (cut-trace short). Be careful not to cut adjacent
PCB traces, nor cut too deep into the multi-layer circuit board.
If the cut-trace short on a jumper header is already cut, you can
return the MPB to its default setting by installing a user-supplied
fabricated jumper.
