Note14. The superimposed logarithmic parabola at EWTRP (Pin20) tracks with VPOS, but
not

VAMP settings.
Note15. If f

tracking is enabled, the amplitude of the complete EWDRV output signal (parabola +
DC shift + trapezium) will be changed proportional to I
HREF
. The EWDRV low level of 1.2V
remains fixed.
