Thanks for the replies, my brain suddenly hit upon another solution, use a=
=20
flag variable in the interrupt that the ADC interrupts have finished (each=
=20
channel is read 16 times before incrementing), test the system flag in the=
=20
main body and disable the ADC interrupt, re-enable once ancillary program=20
has finished.

I might try both methods and see which seems better for my uses.
