VDDQ, VTT and VTTREF turnoff (soft-end)
Tracking discharge
The jumper JP2, if placed in the middle, allows the output tracking discharge. When S3 and
S5 are pulled down, VTT discharges VDDQ by sinking 1 A and, at the same time, tracks the
VDDQ remaining half. When VDDQ reaches about 400 mV, the output discharge MOSFETs
are all closed and each rail is finally discharged.
