LIS2DE12 - is it possible to set & reset INT1 & INT2 pins (or any other pin) on wakeup
Hi,
I was looking at LIS2DE12 and I am aware that it can send a wakeup signal to the CPU. In my design I want to enable the power on PMIC chip directly through its enable pin. So I want to do something like this:
- Shake the device
- LIS2DE12 sets its pin to 1 (3V)
- this pin in is connected to PMIC which now powers up the main CPU
- when the device is not moving the main CPU sets the reset signal to LIS2DE12
- LIS2DE12 sets its pin to 0 (0V)
- PMIC powers down the CPU
I read about latching INT1 & INT2 in the specification paper but I am not sure this means this. I also found https://community.st.com/s/question/0D53W000012QA5NSAW/lis2de12-interrup-on-wakeup but I am not sure if the same case is described there.
Is it possible to make such operation? Just set some pin to 1 when wakeup is triggered and then reset it with another pin.
If this is not possible LIS2DE12 is there any other IC that works like this?
Thanks,
Matej
