Output ALERT* (pin 7) seems to assert low after Power on reset. I wasn't expecting that behavior. No where in the data sheet does it state that the power on default of the ALERT* pin is low. Whey does the chip power up with ALERT* pin low?
I don't know what is triggering it. It shouldn't be triggered. The chip isn't programmed yet. Just powering up. All temp sensors are connected and functional. And nothing out of default temperature range.
I haven't done any configuration yet. When I do apply my application configuration ALERT pin goes high. As it should, because condition doesn't exist for ALERT to be asserted. Why on power-up does a condition exist to assert it?
I've finished my probe of the ALERT status register before I apply any configuration. The status register 0x02 right after POR has a value of 0x08, which indicates flag RLOW is set on power-up. This would indicate that Remote Temperature Sensor reads below Remote Low Temperature Setpoint Register 0x08, 0x14 (POR default of 0degC). This is not possible since I'm at room temperature. After I read the ALERT status register the ASSERT* line (pin 7) goes high as expected. Any thoughts about what is going on here to set RLOW flag?
