Device 16, 30 Functions 0, 1, 4, 5
The Device 16 and 30 Function 0, 1, 4 and 5 contains Thermal Control registers. The 
registers in Device 16 Functions 0, 1, 4, 5 are identical to those in Device 30 Functions 
0, 1, 4, 5, respectively. The Device 16 Function 0, 1, 4 and 5 registers address iMC 0 
Channel 2, 3, 0 and 1, while the Device 30 Function 0, 1, 4 and 5 registers address iMC 
1 Channel 2, 3, 0 and 1.
