5.4.5 Threshold registers
5.4.5.1 Introduction
These four registers are used to store the user-programmable lower and upper threshold values. The
inverter bit and the mask bit to mask the interrupt are stored in the TRC registers.

Field Description
0–15 Reserved
A write of any value has no effect. The read value is always 0.
16
THREN
Threshold enable
When set, this bit enables the threshold detection feature for the selected channel.
17
THRINV
Invert the output pin
Setting this bit inverts the behavior of the threshold output pin.
18 Reserved
Must be kept at 0.
19–24 Reserved
A write of any value has no effect. The read value is always 0.
