Hi!

I'd like to configure the 3V3 output to produce 2.4V for the sensors on our PCB. I haven't found an API (sys_power_mgr?) or a handy dg_config define for this yet, but I did find register LDO_CTRL1_REG in the data sheet. Would you recommend I set the appropriate bit or bits in LDO_CTRL1_REG, maybe something like

REG_SETF(CRG_TOP, LDO_CTRL1_REG, LDO_VBAT_RET_LEVEL, 0x0);

Should I do this in system_init before creating my application's task? Would this configure 3V3 both when the 1468x is active and also when it is in extended sleep?

Thanks for your help!
David
