Hi, Current I am developing a video system based on ADV7441A. The ALSB pin has been pulled low. After reset the chip, I using i2c tools to scan the ADV7441A chip, just found 4 address respond to me.  According to the datasheet, there should 8 i2c address used by adv7441a. Why I can't get the others address (0x30, 0x32, 0x34, 0x36).

 

/ # i2cdetect 0
