1.When power up, the DDSG pin config and DCHG pin config are respectively configured as 0x2d, and the pin automatically outputs high level. How to configure the output low level?
2.After DDSG and DCHG output low level, and then send configuration mode and exit configuration mode commands, and not send DDSG pin config and DCHG pin config to 0X2D, Why do DDSG and DCHG automatically become high level?
