PCA9702, PCA9701, 16-bit/8-bit GPI
The PCA9701/PCA9702 are low power 18 V tolerant SPI General Purpose Input (GPI) shift register designed to monitor the status of switch inputs.
It generates an interrupt when one or more of the switch inputs change state.
The input level is recognized as a HIGH when it is greater than 0.7 VDD and
