2.5V~5.5V電源供電。16個(gè)IO端口中的任何一個(gè)都可以配置為L(cháng)ED模式或GPIO模式。此外，任何GPIO都可以單獨配置為輸入或輸出。
通電后，16個(gè)IO端口配置默認為GPIO輸出，默認狀態(tài)根據AD0和AD1決定。所有配置為輸入的IO端口都會(huì )持續監控狀態(tài)變化，并具有8μs的防抖動(dòng)時(shí)間，IO口的變化由INTN輸出指示。當GPIO狀態(tài)通過(guò)I2C接口被讀取時(shí)，INTN輸出被清除。
當IO端口配置為L(cháng)ED模式時(shí)，可以通過(guò)I2C接口將LED驅動(dòng)器的電流設置在0~IMAX之間，并可以以該值除以256步進(jìn)行線(xiàn)性調光。默認最大電流（IMAX）為37mA，可在全局在控制寄存器中更改IMAX。
