Camera and I2C question about TDA4

Part Number: TDA4VH-Q1

Hi,

TI expert,

In iss_sensors.c, I see that setupI2CInst() and I2C_open() are called in the IssSensor_DeserializerInit() function, and then I2C_close() is called in the IssSensor_PowerOff() function.

I would like to know it is necessary to close an I2C after it is opened? Will it be a problem if it is on all the time?

Thanks.
