Each bit of the following registers disables a peripheral block, either by gating its system
clock input or by removing power from the block.
The default state of the low-power operational amplifier is OFF. To use the low-power
operational amplifier, clear the TRAM bit by turning it ON. Clearing this bit might inter-
fere with normal ADC measurements on ANA0 (the LPO output). 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.
TRAM— Low-Power Operational Amplifier Disable
0 = Low-Power Operational Amplifier is enabled (this applies even in STOP mode).
1 = Low-Power Operational Amplifier is disabled.
Reserved—Must be 0.
LVD/VBO— Low-Voltage Detection/Voltage Brownout Detector Disable
0 = LVD/VBO Enabled
1 = LVD/VBO Disabled
The LVD and VBO circuits are enabled or disabled separately to minimize power 
consumption in low-power modes. The LVD is controlled by the LVD/VBO bit only in all
modes. The VBO is set by the
Program Memory Address 0000H.
