2.4.2
For the ROM version, two possible operating modes exist: with and without voltage regulator. Using the voltage
regulator, low power consumption will be obtained even with supply voltages above 2.4V. Without the voltage
regulator (i.e. VREG short-circuited to VBAT), a higher speed can be obtained.

voltage regulator.
