Thank you very much!
1. But I thinke the answer of question 1 and 5 seem contradictory. Can Software initialization reset bit(bit 7 of 0x1C) reset the whole CPU of TVP5150?
2. I have try, the settings are: 0x1C = 0x80; 0x1D = 0x80; but after set, I read and get the value: 0x1C = 0x00; 0x1D = 0x80; and the TVP5150 is not reset. What may be the reason?
