BOOST STANDBY MODE
User can stop the Boost Converter operation by writing the
Enables register bit EN_BOOST low. When EN_BOOST is
written high, the converter starts for 10 ms in PFM mode and
then goes to PWM mode.
BOOST OUTPUT VOLTAGE CONTROL
User can control the Boost output voltage by boost output 8-
bit register.
