Output
3.3V
SUS
Signals the platform board to get into the S5 state
and to power down the core well including the DRAM
power.
Output
3.3V
SUS
Signals the platform board that the SoC has entered
the S3 state and that the SoC core-well supplies can
be powered down. The DRAM power must remain on
Output
3.3V
SUS
Signals the platform board to power down the
powering to the Gigabit Ethernet PHY circuitry.
This signal is non-functional and is always
This signal is non-functional and is always
deasserted: logic high state.
Output
3.3V
SUS
Used as the platform board reset.
Output
3.3V
SUS
Indicates to the platform board that a low-power
state (S5) is entered soon. The platform needs to
work from the SUS well only.
