Example: Send a MAC Gauging() to enable/disable firmware control of the CHG/DSG/PCHG FETs via
ManufacturerBlockAccess().
1. With firmware control of the CHG/DSG/PCHG FETs enabled, send Gauging() (0x0022) to
ManufacturerBlockAccess().
(a) SMBus word write. Command = 0x00. Data = 00 22
2. FET Control is disabled, ManufacturingStatus()[FET_EN] = 0.
Example: Read HardwareVersion() (0x0003) via ManufacturerBlockAccess()
1. Send HardwareVersion() to ManufacturerBlockAccess().
(a) SMBus block write. Command = 0x00. Data sent = 00 03
2. Read the result from ManufacturerData().
(a) SMBus block read. Command = 0x06. Data read = 00 01
(b) That is 0x0100, HardwareVersion() 100.

    这是印刷错误，It should be 0x23 which is ManufacturerData().
