ROM circuit version with regulator on

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.
