Control registers

31/65

Note:

bit “jump” is automatically reset after use.

maxdyn: max dynamic magnitude allowed on YCrCb inputs for encoding.

(*) 0 = 10hex to EBhex for Y, 10hex to F0hex for chrominance (Cr,Cb)

1= 01hex to FEhex for Y, Cr and Cb

Note:

In any case, EAV and SAV words are replaced by blanking values before being fed to the

luminance and Chrominance processing.

bypass_sync_corr: tst_dac bypass mode with sync correction. This is a test mode in which

data coming from port tst_dac can be output with or without sync correction and given to the

dacs.

(*) 0 = There is no sync correction applicable to the data coming from tst_dac.

1 = Sync correction takes place before setting the dacs provided tst_ana(0) is set to ‘1’.

Please note that in this case only 8 MSBs are used to generate a 10-bit sync corrected

output from the filter.

Automatic line insert mode.

The 2nd field of the frame following the writing of this value is

increased. Line insertion is done after line 245 in 525/60 and

after line 290 in 625/50.

“lref” and “ltar” are ignored.(1)

Automatic line skip mode.

The 2nd field of the frame following the writing of this value is

decreased. Line suppression is done after line 245 in 525/60

and after line 290 in 625/50.

“lref” and “ltar” are ignored.(1)

Not to be used.

Two lines are skipped (inserted) in 525/60 and four lines in 625/50 standards
