The preset value for D7 is 1. The preset values for D0 to D6 are 0.
The content of the sub address [05H] varies according to the [MODE] setting.
While the Read bus for acknowledging EDTV2 signals is being used, VCL is fixed
to 4fH.
EDTV2 signals acknowledging function is only guaranteed for high-field signal
inputs. As for Iow-field and ghost signal inputs, the acknowledging function
must be carefully evaluated by the user before actual usage.
