CC1310: Allowable current draw from GPIO pins when in Standby Mode

Part Number: CC1310

Hi,

I have an application whereby I'm supplying power to an accelerometer from a CC1310 GPIO output (Either DIO_15 or DIO_10, if that affects your answer!).  The accelerometer draws ~6uA when running.  The CC1310 hardware has 2.5V on VDDS and is configured to run from either the internal DC-DC or the internal LDO, depending on whether it's in Active (DC-DC) or Standby (Internal LDO) modes.

Can I just verify that the CC1310 is happy to supply ~6uA from a GPIO pin when running from the internal LDO, when in Standby Mode?  I didn't see anything in the Datasheet or Technical Reference Manual to suggest there was any difference in maximum allowable current draw on a GPIO pin when run from the internal LDO rather than the DC-DC.

Thanks,

Robin
