6 bytes in FQ1216ME_MK3?? I can only see DB1, DB2, CB, BB, and AB (it's five)... The chargepump, CP, is bit 6 and PLL tuning, OS, is bit 0, both in the CB byte... are we looking at the same document?? /Corax ------- This is from an I2C-logger running on windows (don't trust your life on the comments ;-))... FQ1216AME MK4, PAL-BG (I think I read that you should first set the tuner to high frequence before the wanted one to ensure good operation, but is not sure if it was this tuner, another one, or the decoder chip. This would at least explain the first write.)
