TMDS181: Handling for SCL_CTL and SDA_CTL

Sadanori Kato

Part Number: TMDS181

Hi,

Could you please tell me your recommended handling for the pins of SCL_CTL and SDA_CTL if using TMDS181 with the pin strap mode(I2C_EN/PIN = low) ?
Should those pins be connected to GND ? Or should those pins be connected to VCC with the pull-up resistors ?

Best regards,
Kato

Hello Sadanori

Yes, these pins should be connected to GND. When I2C_EN/PIN= 0 the write action is ignored, but you can be sure that you won't have any I2C transaction with these pins connected to GND.

Francisco
