surements 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 power-on reset sequence. Other system reset events do
not affect it.
