Hello, I'm running into some problems getting the fxls8471q to wake up in spi mode. I have RST tied to vss. The SA0 line is going to a pin on the MK10DN512VLL10 which happens to power up as an analog input. Although it is somewhat floating, there is a weak pull up. How exactly does the FXLS8471Q determine that pin is floating? Is it trying to pull up/pull down weakly? I see INT1 going low for 500nS, but I only see SA0 rising to VDD over a period of 2mS. Apparently it is waking up up in I2C mode, because I can't read anything from the WHO_AM_I register.
