Avoid using software conversion trigger as it doesn't work very well for
differential mode on some versions of PCI230/260.  Use Z2 timer 2 output
instead and toggle the output in software to trigger a conversion.  Note
that the ADC busy bit only works for software triggers in non-FIFO mode,
so for AI INSN_READ, use the FIFO and the FIFO status bits to check when
the conversion is complete.
