RST pin needs POR circuit， pull up resistance(4.7K) and capacitor(recommended not exceed 1.1nF ).

Refer to the application circuit.in datasheet.

Hi Allen，

Thanks your support,

Customer wants to know that they only wants to use the I2C to connect the CPU and not to use the UART, Can the current design support it? Thanks a lot.

Best regards
