，请问这两者发送命令的区别是什么，都是使用I2C发送命令，为什么左侧的不能发送COMMANDS的内容,或者说使用I2C发送这两者命令之间的区别是什么
您好，The commands buttons are additional commands that are available in BQ40Z50
ManufacturerAccess is an SBS command that is read/write. The behavior is defined by TI(manufacturer) and detailed in the TRM.
commands 命令有限， Use the advanced comm SMB for commands that do not have a button or register display.
