Subsection Ready Register (Index 26h)
Note: The ready bits are read only; writing to REF, ANL, DAC, ADC will have no effect. These bits indicate the status for the
AD1886A subsections. If the bit is a one, that subsection is “ready.” Ready is defined as the subsection able to perform in its
nominal state.

AD1886A Power-Down Modes. The first three bits are to be used individually rather than in combination with
each other. The last bit, PR3, can be used in combination with PR2 or by itself. The mixer and reference cannot
be powered down via PR3 unless the ADCs and DACs are also powered down. Nothing else can be powered up
until the reference is up.
PR0—Power-Down ADC
PR1—Power-Down DAC
PR2—Power-Down Analog Mixer
PR3—Power-Down V
PR4—Power-Down AC-Link
PR5—Power-Down Internal Clock
PR6—Power-Down Headphone
PR5 has no effect unless all ADCs, DACs, and the AC-Link are powered down. The reference and the mixer can be
either up or down, but all power-up sequences must be allowed to run to completion before PR5 and PR4 are both set.
In multiple-codec systems, the master codec’s PR5 and PR4 bits control the slave codec. PR5 is also effective in
the slave codec if the master’s PR5 bit is clear, but the PR4 bit has no effect except to enable or disable PR5.
