DESCRIPTION
Power Indicator: Indicates the power status for each slot at
downstream port. PWR_IND [x] is correspondent to Port x, where
x=1,2,3. They are active-high signals. The pins have internal pull-
down.
Attention Indicator: Indicates the attention status for each slot at
downstream port. ATT_IND [x] is correspondent to Port x, where
x=1,2,3. They are active-high signals. ATT_IND[3:2] have internal
pull-down.
Attention Button: When asserted high, it represents the attention
button has been pressed for the slot at the downstream port. ATT_BTN
[x] is correspondent to Port x, where x=1,2,3.
Presence Detected Change: When asserted low, it represents the
device is present in the slot of downstream ports. Otherwise, it
represents the absence of the device. MRL_PDC [x] is correspondent
to Port x, where x=1,2,3.
SLOT Power Enable (Active LOW): Indicates the enable status of
the power connecting to the associated slot. PWR_ENA [x] is
correspondent to Portx, where x=1,2,3. They are active-low signals.
Pins are set to “000” by default.
SLOT Power Fault: When asserted high, it indicates a power fault on
one or more supply rails. PWR_FLT [x] is correspondent to Port x,
where x=1,2,3.
DESCRIPTION
EEPROM Clock: Clock signal to the EEPROM interface.
EEPROM Data: Bi-directional serial data interface to and from the
EEPROM. The pin has internal pull-up.
SM Bus Clock: System management Bus Clock. Pin has an internal
pull-down.
SM Bus Data: Bi-Directional System Management Bus Data.
Full-Scan Enable Control: For normal operation, SCAN_EN is an
output with a value of “0”. SCAN_EN becomes an input during
manufacturing testing.
Port PHY Error Status: These pins are used to display the PHY Error
status of the ports. When PORTERR is flashing (alternating high and
low signals), it indicates that a PHY error is detected. When it is low,
no PHY error is detected. PORTERR [x] is correspondent to Port x,
where x=0,1,2,3.
General Purpose Input and Output: These eight general-purpose
pins are programmed as either input-only or bi-directional pins by
writing the GPIO output enable control register.
When SMBus is implemented, GPIO[7:5] act as the SMBus address
pins, which set Bit 2 to 0 of the SMBus address.
Test1: This pin is for internal test purpose. Test1 should be tied to
ground through a pull-down resistor.
Test2/3/4/5: These pins are for internal test purpose. Test2, Test3,
Test4 and Test5 should be tied to 3.3V through a pull-up resistor.
Test6: This pin is for internal test purpose. Test6 should be connected
an (475 ohm +/- 1%) external resistor to Vss.
Test7: This pin is for internal test purpose. Test7 should be tied to
ground through a pull-down resistor (5.1k ohm).
Not Connected: These pins can be just left open.
