In all the tables contained in this manual, Power rails are named with the following meaning:
_RUN: Switched voltages, i.e. power rails that are active only when the board is in ACPI s S0 (Working) state. Examples: +3.3V_RUN, +5V_RUN.
_ALW: Always-on voltages, i.e. power rails that are active both in ACPI s S0 (Working), S3 (Standby) and S5 (Soft Off) state. Examples: +5V_ALW, +3.3V_ALW.
