Hi, I'm creating a design using 4x ADV7182A devices on a single I2C bus. The ADV part only allows 2 unique addresses based on the state of the ALSB pin. Can I toggle the ALSB pin on the device during operation to change its address on the fly?
My thinking is that I could toggle the ALSB pins like chip selects so I can talk to all 4 devices without using isolators. I would configure one device at 0x40, and the other three at 0x42, then communicate to 0x40.
Is this possible? If so, is there a minimum time delay between toggling the ALSB pin and talking to the ADV part?
