Notes:
internal regulated core voltage at Vreg mainly feeds circuitry on ETRX2, the Vreg module pin may only be
slightly loaded and without feeding noise to Vreg. Vreg is not available in Power Mode 3 (see the AT
Command Manual for details of power modes).
Where the dc regulator option is mounted Vreg is connected to the regulator option output instead and the
internal regulated core voltage is not accessible.
