To enable the regulator the VREG_EN pin needs to be either pulled high or left unconnected. This preserves compatibility
with BlueCore2-ROM since the corresponding pin on BlueCore2-ROM was designated a not connect pin. In
BlueCore4-ROM the regulator is permanently on, replicating BlueCore2-ROM that has no regulator enable pin.
