Address byte bits:
• Bit 2 is read/write bit (1=read, 0=write).
• Bits marked as X are don’t care bits.
• The instant write commands write values to CR1 and CR2 registers for right and left channels respectively.
These values can be read by using the specified read commands for CR1 and CR2 registers.
