The ready bits are read only; writing to REF, ANL, DAC, ADC will have no effect. These bits indicate the status for the AD1888 subsections. If the bit is a 1, then
that subsection is
ready
.
Ready
is defined as the subsection able to perform in its nominal state. All registers not shown and bits containing an X are assumed to be reserved.

Codec Power-Down Modes. The first three bits are to be used individually rather than in combination with each
other. 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.
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.
PR[6:0]
EAPD
External Audio Power-Down Control. Controls the state of the EAPD pin.
EAPD = 0 sets the EAPD pin low, enabling an external power amplifier (reset defaults).
EAPD = 1 sets the EAPD pin high, shutting off the external power amplifier.
