Introduction
BF6910AX/11AX is based on 10/14/22 chip, which can be used to detect the proximity sensorOr touch. Its built-in MCU, can be configured flexibly; can be achieved through the configuration button, roller, slide bar, and other applications.
10/14/22 keys can be run independently, and each button can be written to the corresponding special function register
To adjust the sensitivity.
BF6910AX/11AX communication with the host through the IIC.
BF6910AX/11AX contains a single frequency of 24MHZ microcontroller core and some other peripheral equipment, as shown in Figure 1
