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.
This register is only reset during a POR sequence. Other system reset events do not affect
it.
LPO—Low-Power Operational Amplifier Disable
0 = LPO is enabled (this applies even in STOP mode).
1 = LPO is disabled.
Reserved—Must be 0.
VBO—Voltage Brownout 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
TEMP—Temperature Sensor Disable
0 = Temperature Sensor Enabled
1 = Temperature Sensor Disabled
ADC—Analog-to-Digital Converter Disable
0 = Analog-to-Digital Converter Enabled
1 = Analog-to-Digital Converter Disabled
COMP—Comparator Disable
0 = Comparator is Enabled
1 = Comparator is Disabled
Reserved—Must be 0.
Asserting any power control bit disables the targeted block, regardless of any enable bits
contained in the target block’s control registers.
