A/D RC Mode
The minimum time is the
amplifier settling time. This
may be used if the "new" input
voltage has not changed by
more than 1 LSb (i.e., 20.0 mV
@ 5.12V) from the last sam-
pled voltage (as stated on

If the A/D clock source is
selected as RC, a time of T
is added before the A/D clock
starts. This allows the SLEEP
instruction to be executed.
