H A Dsmsc47m192.rst35 These chips support 3 temperature channels and 8 voltage inputs
36 as well as CPU voltage VID input.
44 Voltages are scaled such that the nominal voltage corresponds to
46 each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
47 is 1 bit per (nominal voltage)/192.
48 Both voltage and temperature values are scaled by 1000, the sys files
51 The +12V analog voltage input channel (in4_input) is multiplexed with
52 bit 4 of the encoded CPU voltage. This means that you either get
53 a +12V voltage measurement or a 5 bit CPU VID, but not both.
59 The temperature and voltage readings are updated once every 1.5 seconds.
