Functional Description
3.6.1.1 Disabled Mode (1)
In disabled mode, the analog comparator is non-functional and consumes no power. The
output of the analog comparator block (ACO) is zero in this mode. It is possible to further
reduce power consumed by disabling the peripheral clock to the comparator logic. This is
a function of the system integration module, or SIM.
3.6.1.2 Continuous Mode (2A and 2B)
The analog comparator block is powered and active. ACO may be optionally inverted,
but is not subject to external sampling or filtering. Both window control and filter blocks
are completely bypassed. The SCR[COUT] bit is updated continuously. The path from
comparator input pins to output pin is operating in combinational (unclocked) mode.
COUT and COUTA are identical.
