Hi all,
A question about PCA9538 INT behavior below,
1. Our GPIO P0-7 are all LOW in standby mode. (by external HW logic)
so the default input value is "0000 0000"
2. when power on , P0-7 is 1111 1100. (P0-P5 is Pull high by external logic)
3. If we want to trigger INT pin in main power on, when p0-p5 is going to 1 from 0.
do we need to invert default setting of p0-p5 in standby mode? so the default input becomes "1111 1100"
Thanks
