Comparator Operation
Operational Amplifier Operation
Interrupts
PS028702-1210
•
The comparator output reflects the relationship between the non-inverting input and the
inverting (reference) input. If the voltage on the non-inverting input is higher than the
voltage on the inverting input, the comparator output is at a high state. If the voltage on the
non-inverting input is lower than the voltage on the inverting input, the comparator output
is at a low state.
To operate, the comparator must be enabled by setting the CMPEN bit in the comparator
and op-amp register to 1. In addition the CINP and CINN comparator input alternate func-
tions must be enabled on their respective GPIO pins. For more information, see the
Alternate Functions
The comparator does not automatically power-down. To reduce operating current when
not in use, the comparator is disabled by clearing the CMPEN bit to 0.
To operate, the operational amplifier must be enabled by setting the OPEN bit in the com-
parator and op-amp register to 1. In addition, the OPINP, OPINN and OPOUT alternate
functions must be enabled on their respective general-purpose I/O pins. For more informa-
tion, see the
The logical value of the operational amplifier output (OPOUT) is read from the Port 3 data
input register if both the operational amplifier and input pin Schmitt trigger are enabled.
For more information, see the
fier generates an interrupt via the GPIO Port B3 input interrupt, if enabled.
The output of the operational amplifier is also connected to an analog input (ANA3) of the
ADC multiplexer.
The operational amplifier does not automatically power-down. To reduce operating cur-
rent when not in use, the operational amplifier is disabled by clearing the
comparator and op-amp register to 0.
When the operational amplifier is disabled, the output is high impedance.
The comparator generates an interrupt on any change in the logic output value (from 0 to 1
and from 1 to 0). For information about enabling and prioritization of the comparator
interrupt, see the
Operating the operational amplifier open loop (no feedback) effectively provides
another on-chip comparator.
