PS1, Line 65: 	return 0x90; /* This will return 1.6V which is expected value for Delta Lake */
> This function is supposed to return the processor voltage in 100mV units. […]

In this field, BIT7 sets to 1 so that other bits represent cpu voltage times 10.
0x90h = 0x80h + (1.6 * 10) = 0x80h + 16 = 0x80h + 0x10h
