Description
Comparison Interrupt Mode
This field specifies the mode by which the interrupt comparison is made.
Value Description
0x0 Always
This mode generates an interrupt every time the ADC conversion
data falls within the selected operational region.
0x1 Once
This mode generates an interrupt the first time that the ADC
conversion data enters the selected operational region.
0x2 Hysteresis Always
This mode generates an interrupt when the ADC conversion
data falls within the selected operational region and continues
to generate the interrupt until the hysteresis condition is cleared
by entering the opposite operational region.
Note that the hysteresis modes are only defined for CTC
encodings of 0x0 and 0x3.
0x3 Hysteresis Once
This mode generates an interrupt the first time that the ADC
conversion data falls within the selected operational region. No
additional interrupts are generated until the hysteresis condition
is cleared by entering the opposite operational region.
Note that the hysteresis modes are only defined for CTC
encodings of 0x0 and 0x3.
