succession. The interrupt routine can be set up to average inputs and to detect out-of-range
signals.
A/D conversion can be provided sequentially on additional channels by adding a multi-
plexer between the comparators and the Rabbit 3000 PG5 input capture pin.
At the same time that an A/D conversion takes place, the PowerCore module exercises
one-third of a calibration routine where the 2.5 V reference is used to recalibrate the A/D
converter every 7.5 ms. Part of the calibration routine reads the thermistor, whose temper-
ature reading is also available.
This A/D conversion can be used to monitor slow-moving analog voltage outputs such as
those from sensors or potentiometers.
