Field
Description
WDGnL
Reading this field indicates whether an interrupt has been generated due to the converted value being
lower than the programmed lower threshold.
0 Converted value is higher or equal to the programmed lower threshold (no interrupt generated)
1 Converted value is lower than the programmed lower threshold (interrupt is generated)
WDGnH
Reading this field indicates whether an interrupt has been generated due to the converted value being
higher than the programmed higher threshold.
0 Converted value is lower or equal to the programmed higher threshold (no interrupt generated)
1 Converted value is higher than the programmed higher threshold (interrupt is generated)
