operational amplifier (LPO) is OFF. To use the LPO, clear the LPO bit, turning it ON.
Clearing this bit might interfere with normal ADC measurements on ANA0 (the LPO out-
put). This bit enables the amplifier even in Stop Mode. If the amplifier is not required in
Stop Mode, disable it. Failure to perform this results in Stop Mode currents greater than
specified.
Note: This register is only reset during a POR sequence. Other system reset events do not affect it.

Description
Low-Power Operational Amplifier Disable
0 = LPO is enabled (this applies even in Stop Mode).
1 = LPO is disabled.
Reserved
These bits are reserved and must be programmed to 00.
Voltage Brown-Out Detector Disable
This bit and the VBO_AO Flash option bit must both enable the VBO for the VBO to be active.
0 = VBO enabled.
1 = VBO disabled.
Temperature Sensor Disable
0 = Temperature Sensor enabled.
1 = Temperature Sensor disabled.
Analog-to-Digital Converter Disable
0 = Analog-to-Digital Converter enabled.
1 = Analog-to-Digital Converter disabled.
Comparator Disable
0 = Comparator is enabled.
1 = Comparator is disabled.
Reserved
This bit is reserved and must be programmed to 0.
