Dir Description
2
Input/ I C Slave Address input / Transmit Power Sense output pin.
Output When RESET# is low, this pin is used as an input to latch the
2
I C sub-address. The level on this pin is latched when the
RESET# pin transitions from low to high.
When RESET# is high, this pin is used as the TPWR output,
indicating that the selected Rx-port is has 5V present. When
none of the Rx ports are selected, this signal is low.
See page 15 for more information.
2
Input/ I C Selection input / Interrupt output pin.
Output When RESET# is low, this pin is used as an input to latch the
External Port Detection signal. The level on this pin is latched
when the RESET# pin transitions from low to high.
When this pin is high during reset, the external pins
EPSEL1/LSCL and EPSEL0/LSDA are used to select the Rx-
port as EPSEL[1:0].
When this pin is low during reset, the internal local I
is used to select the Rx-port.
After reset, this pin becomes the Interrupt output.
This is an open-drain output and requires an external pull-up.
See page 14 for more information.
Input Reserved for use by Silicon Image and must be tied low.

Dir Description
Input Reset Pin (Active LOW). Certain configuration inputs are
latched when RESET# transitions from low to high. See page
14 for more information.
2
Input Local I C Clock / External Port Select 1. When I2CSEL is high,
2
this becomes the Local I C bus clock pin, LSCL. When I2CSEL
is low, this becomes the external port select pin, EPSEL1. True
open drain, so does not pull to ground if power not applied. An
external pull-up is required.
See page 14 for more information.
2
Input/ Local I C Data / External Port Select 0. When I2CSEL is high,
2
this becomes the Local I C bus data pin, LSDA. When I2CSEL
Output
is low, this becomes the external port select pin, EPSEL0. True
open drain, so does not pull to ground if power not applied. An
external pull-up is required.
See page 14 for more information.
Description
Input/ HDMI compliant CEC I/O used to interface to CEC devices.
Output CEC electrically compliant signal. This pin connects to the CEC
signal of all HDMI connectors in the system.
As an input, the pad acts as a LVTTL Schmitt triggered input
and is 5V tolerant. As an output, the pad acts as an NMOS
driver with resistive pull-up. This pin has an internal pull-up
resistor.
Input/ CEC interface to local system. True open-drain. An external
Output pull-up is required. This pin typically connects to the local CPU.
