NOTE
Refer to the chip configuration section for the source of sample/
window input.
The analog comparator block is powered and active. CMPO may be optionally inverted,
but is not subject to external sampling or filtering. Both Window Control and Filter
Blocks are completely bypassed. SCR[COUT] is updated continuously. The path from
comparator inputs pins to output pin is operating in combinational (unclocked) mode.
COUT and COUTA are identical.
For control configurations which result in disabling the Filter Block, refer to Filter Block
Bypass Logic diagram.
