APPENDIX 4
REGISTER VALUES
The ADV7177/ADV7178 registers can be set depending on the
user standard required.
The following examples give the various register formats for
several video standards.
In each case the output is set to composite o/p with all DACs
powered up and with the
BLANK
input control disabled. Addi-
tionally, the burst and color information are enabled on the
output and the internal color bar generator is switched off. In
the examples shown, the timing mode is set to Mode 0 in slave
format. TR02–TR00 of the Timing Register 0 control the tim-
ing modes. For a detailed explanation of each bit in the com-
mand registers, please turn to the Register Programming section
of the data sheet. TR07 should be toggled after setting up a new
timing mode. Timing Register 1 provides additional control over
the position and duration of the timing signals. In the examples,
this register is programmed in default mode.
