Power rails naming convention
In all the tables contained in this manual, Power rails are named with the following meaning:
_S: Switched voltages, i.e. power rails that are active only when the board is in ACPI
’
s S0 (Working) state. Examples: +3.3V_S, +5V_S.
_A: 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_A, +3.3V_A.
Other suffixes are used for application specific power rails, which are derived from same voltage value of voltage switched rails, if it is not differently stated (for
example, +5V
HDMI
is derived from +5V_S, and so on).
