Hi,
As the title said, I need more GPIOs for application, and could I use the XL1 and XL2 ?
What happen when use RC oscillator instead?
Thanks.

You'll have to add the current required for the HF_CLK. The datasheet says that HF_CLK oscillator will consume around 470uA when it needs to drive for any peripheral, 25 uA if it is idle. I guess (not sure) HF_CLK providing clock to LF_CLK accounts to it being active, so 470 uA more, which is quite a bit. I hope someone can clarify this.
Yeah, couldn't come up with a realistic low power use case where the synthesized clock would be useful.
