HREF
The TC90A58F has a built-in horizontal PLL. The following parameters can be set using the I
The TC90A58F can also be used as a 10-bit AD converter. This setting can be made using the M10B bit in
Note that when the device is used as a 10-bit AD converter, only two channels (the Y and Cb signals) are
When the TC90A58F is used as a 10-bit AD converter, only certain functions can be used.
