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?For example,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?OrDo we have to reset the ADV739x (Software reset 0x17 bit) and write all register settings again for re-enabling CVBS output?
Thank you!Best regards.Tamu
Software resets will set all registers to their default states. So better you can control the 0x00 register alone for DAC1 power on/off.
Thank you !
