  I would suspect, if they're labeled "sense", that they'd be the remote
sensing leads for the power supply...so that regulation isn't affected
by the I^2R drop on the way to the CPU.  Most "pprogrammable" voltage
regulators for multivolatege CPU cores use binary voltage selection
mechanism using from two to six bits.
