Huh ? Can you elaborate please ? Were the other pins driving current or
were their input protection networks (mis)used at the time ? How bad was
the influence (knowing that 7 bits absolute accuracy from a direct A/D
using PIC pins only - not a2d.asm - is expected). In English: was it worse
than about 30 mV at Vdd = 5V ?
