How to interpret the three numbers in 'ADV7613 Register Settings Rcommendations'

Hi,

How to interpret the three numbers in 'ADV7613 Register Settings Rcommendations'? For example, '98 F4 80', it's three hex number? And it's a 24-bit I2C address? So, the I2C address of ADV7613 is 24-bit?

I'm feel frustrated.

Thanks.
