21 Comparators
The SOC supports 19 Low power comparators which can be used to wake the system
from low power states. Two types of comparators are supported, a Low power, low
performance version and a high power high performance version. Analog Inputs [5:0]
are connected to high performance comparators and Analog Inputs [18:6] are
connected to low power comparators.
Each comparator can be powered down to achieve even lower power. Comparator
reference supply is selectable between the internal VREF (0.95V +/- 10%) and an
external user supplied reference (AR input).
