TI中文支持网你好，
请教cmd 0x44 0X0056数据位变更，MCU对SMBus block怎么操作，我们按照一下还是有问题，能否举例，谢谢
Example: Read Chemical ID() (0x0006) via ManufacturerBlockAccess() 1. Send Chemical ID() to ManufacturerBlockAccess(). a. SMBus block write. Command = 0x44. Data sent = 06 00 (Data must be sent in Little Endian.) 2. Read the result from ManufacturerBlockAccess(). a. SMBus block read. Command = 0x44. Data read = 06 00 00 01 (Each data entity is returned in Little Endian.) b. The first 2 bytes, “06 00”, is the MAC command. c. The second 2 bytes, “00 01”, is the chem ID returning in Little Endian. That is 0x0100, chem ID 100.
