ADV7280 Script writes to a read-only register.

I'm working with the EVAL-ADV7280EBZ kit and the "DVP Eval Latest Source 10-14-11" software.  I'm looking at the AutoDetect_CVBS_Single_Ended_In_Ain_1_YPrPb_Out.py script.  About halfway down the script there is this line:

 

writeRegs(0x42, 0x13, [0x0,], [1, 8])

 

This appears to be attempting to write to the "Status 3" register which is read only. Why?
