APPENDIX 8—RECOMMENDED REGISTER VALUES

The ADV7174/ADV7179 registers can be set depending on the

user standard required. The power-on reset values can be found

in Figure 37.

The following examples give the various register formats for

several video standards. In each case, the output is set to compos-

ite output with all DACs powered up and with the input control

disabled. Additionally, the burst and BLANK color information

is 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 timing modes. For a detailed explanation of each bit

in the command registers, refer to the Register Programming

section. 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.
