Note:
The Get UDID command depends on whether or not this is a Directed or General
command.
The General Get UDID SMBus transaction supports a constant command value of 0x03.
The Directed Get UDID SMBus transaction supports a Dynamic command value equal to
the dynamic SMBus address with the LSB bit set.
Bit 0 (LSB) of Data byte 17 is always 1b.
