Description
Reserved
Write of any value has no effect, read value is always 0.
THREN: Threshold enable
When set, this bit enables the threshold detection feature for the selected channel.
THRINV: Invert the output pin
Setting this bit inverts the behavior of the threshold output pin.
Reserved
Must be kept at 0.
Reserved
Write of any value has no effect, read value is always 0.
