Examples:

Reading an SMB Command.

  • Read SBData Voltage (0x09)
    • SMBus Read Word. Command = 0x09
    • Word = 0x3A7B, which is hexadecimal for 14971mV

Sending a MAC Gauging() to enable IT via ManufacturerAccess().

  • With Impedance Track™ disabled, send Gauging() (0x0021) to ManufacturerAccess().
    • SMBus Write Word. Command = 0x00. Data = 00 21

Reading Chemical ID() (0x0006) via ManufacturerAccess()

  • Send Chemical ID() to ManufacturerAccess()
    • SMBus Write Block. Command = 0x44. Data sent = 00 06
  • Read the result from ManufacturerData()
    • SMBus Read Block. Command = 0x44. Data read = 06 00 10 12
    • That is 0x1210, chem ID 1210
