which is indicated by the GO/DONE bit of the
ADCON0 register remaining in the GO state
indefinitely. This condition can be cleared by
a device Reset or by clearing the ADON bit
of the ADCON0 register.
Offset error is 3 LSb typical, 7 LSb maximum,

ous conversion is greater than 100 ms, take
two ADC conversions and discard the first.
