24 embedded into Baikal-T1 process, voltage and temperature sensors. PVT IP-core
29 compile-time configurable due to the hardware interface implementation
35 the threshold status bits. Depending on the measurements timeout settings
40 in alarm-less configuration the data conversion is performed by the driver
41 on demand when read operation is requested via corresponding _input-file.
44 ----------------------
46 Temperature is measured with 10-bit resolution and reported in millidegree
48 temperatures that don't need any user-space adjustments. While the data
49 translation formulae isn't linear, which gives us non-linear discreteness,
51 The temperature input is mapped as follows (the last column indicates the input
54 temp1: CPU embedded diode -48.38C - +147.438C
