TPWR_CI2CA
I/O
I2C Slave Address input/Transmit Power Sense Output.
At the end of power -on-reset (POR), this pin is used as an input to latch the I2C sub-address. The level on
this pin is latched when the POR transitions from the asscred state to the de-asserted state. After complec-
tion of POR, this pin is used as the TPWR output, indicating that the selected HDMI input port is receiving an
active TMDS clock. This pin has an internal pull-up to the MICOMVCC33 power supply. If this signal is
pulled-down, a 4.7L

Note: There is a probability the POR logic may power up and not latch the level on this pin. A software
workaround is required to determine the proper I2C slave address.
