FXL6408 Overview
The FXL6408 is an 8−bit I2C−controlled GPIO expander. When configured in Input Mode, the FXL6408 monitors the input ports for data transitions and signals the baseband by asserting the INT pin. The input default values can be programmed independently, allowing customized input detection.
