1) Measurement Definition for Rtt(eff):
Apply VIHac and VILac to test pin seperately, then measure current I(VIHac) and I(VILac) respectively
Rtt(eff) = (VIHac - VILac) /( I(VIHac) - I(VILac))
2) Measurement Defintion for VM:
Measure voltage (VM) at test pin (midpoint) with no load:
delta VM =(( 2* VM / VDDQ) - 1 ) x 100%
