REGISTER VALUES

The ADV7175/ADV7176 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. Ad-

ditionally, 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 timing

modes. For a detailed explanation of each bit in the command

registers, please turn to the register programming section of the

data sheet. TR07 should be toggled after setting up a new tim-

ing 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.
