12.7 Power-down Control/Status register (index 0x26)
This read/write register is used to program power-down states and monitor
subsystem readiness. The lower half of this register is read only status, a ‘1’
indicating that the subsection is ‘ready’. ‘Ready’ is defined as the subsection able to
perform in its nominal state. When this register is written, the bit values that come in
on AC-link will have no effect on read-only bits 0 - 7.
When the ‘Codec Ready’ indicator bit (SDATA_IN slot 0, bit 15) is a 1, it indicates that
the UCB1400 control and status registers are in a fully operational state. The AC ’97
Controller must further probe this Power-down Control/Status register to determine
exactly which subsections, if any, are ready.
