All,
1.) I am examing the SPI_IRQ pin that is coming out of the CC3000.
From the datasheet:
The pin is an output and at reset the line is Hi-Z. After reset this is "Force 1".
2.) What does "Force 1" mean? Does this mean the line is taken high to VIO_HOST (3.3V) when an interrupt is not being generated? Then taken low (ground) when there is an interrupt?
3.) Is there any need to add an external pullup resistor to this pin? ( I am interfacing a +5V based microcontroller with the +3.3V based CC3000.)
Thanks.
