Hi
Is it possible keep GPIO status in LPDS mode?
On datasheet, it says GPIO is input with 500 kΩ pulldown in LPDS mode. For unused GPIO, hold them in a valid state.
I test in LPDS mode,
1. set it to high, the real voltage is 2V
2. Set it to low, the real voltage is 0.55V
So, is GPIO unable keep their status in LPDS mode? Thanks,
Daniel,
Have you taken a look at the Power Measurement example? In this example, there is the lp3p0_plat_ops.c which has functions that help you park pins in LPDS. You can see in this that GPIO9 is configured as WEAK_PULL_DOWN_STD. You should be able to change this to a pull up and it should hold its state in LPDS.
Hope that helps!
