DESCRIPTION

AGA[6:0]

I2C-bus device address deﬁnition. These bits deﬁne the I2C-bus device address

deﬁnition for the automatic control of the I2C-bus loop through gate. The subaddress

auto-increment function reverts from SA = 30 to SA = 0, excluding the AUTOGATE byte

(SA = 31). The AUTOGATE byte can only be accessed via direct subaddress selection

of SA = 31, in which case auto-increment will revert to SA = 0.

AGOF

Autogate function enable. 0 = enable; 1 = disable [The autogate function is not

compatible with the TEA684x tuner devices. For the TEA684x the use of the shortgate

(SGAT) function is advised].
