I have a question related to enable/disable the DAC output of ADV739x.
When we want to control the DAC output enable/disable, how should we control the register settings?
At first, ADV739x works normally. The CVBS outputs correctly.
Then, when we want to disable the CVBS output, can we control the "DAC 1: power on/off" register (0x00 bit = 0) only?
After that, when we want to enable the CVBS output again, can we control the "DAC 1: power on/off" register (0x00 bit = 1) only?
Like above, can we control only the "DAC : power on/off" register for that?
Do we have to reset the ADV739x (Software reset 0x17 bit) and write all register settings again for re-enabling CVBS output?
