AIC3254 Sleep Mode

Hi,

When the codec is not used, I put it in sleep mode, following the datasheet (5.19.1.1.2).  To do that, I write Pg1 Reg 2 D(0)=0 D(3)=1, and then Pg1 Reg 1 D(3)=0.  Is this sequence correct?

As some parts of the codec are powered up in normal use, such as PLL and NDAC/NADC/MDAC/MADC, do I have to power them down before putting the codec in sleep mode?

Best Regards,

  Miguel
