Input DDC I C Clock for respective port.
--- Port " Tx detection " input. Connect 5V input from HDMI connector.
Dir Description
Output Hot Plug Detect Output.
Input Hot Plug Detect Input.
Input / Optical I2C address. When RESET # is '0', pin will be used as an input to latch
Output I2C sub-address.
When RESET # is '1', this pin will be used as an output for TPWR indicating
selected Rx-port is alive.
Input External Port selection input pin. When this pin is '1' external pins, SCL_L and
SDA_L, will be use to select Rx-port as ExPSEL[1:0]. When '0', internal local I2C
register will be used to select Rx-port.
--- Reserved for use by Silicon Image and must be tied low.
Dir Description
Input Reset Pin (Active LOW)
Input Local Configuration / Status I C Clock. When EXTSEL = '1', local CSL will be
used as External port selection pin, EPSEL[1].
Bi-Di Local Configuration / Status I C Data. When EXTPSEL = '1', local SDA will be
used as External port selection pin, EPSEL[0].
Output Master DDC Clock (Open Drain Output) to HDMI receiver.
