Table 31 DORW Page 3

Page 4 of the DORW occupies register addresses R30752 (7820h) to R30759 (7827h).
This page of data is loaded from the third page of DBE memory (20h to 2Fh) when ‘ON’ state
transition is scheduled in Development Mode. This page of data can also be loaded from DBE using
the DBE Read command. Note that DBE Address 20h corresponds to bits 15:8 at the start address
of DORW Page 4; DBE Address 21h corresponds to bits 7:0 at the same DORW address.
The DBE_VALID_DATA register is used to hold a validation field for the DBE data contents. If the
WM8310 configuration data is loaded from the external DBE in response to an ‘ON’ state transition
request in Development Mode, then the DBE_VALID_DATA field is checked to confirm valid DBE
data.
The DBE data is deemed valid if the DBE_VALID_DATA field contains the value A596h. If the DBE is
not connected or contains invalid data, then the WM8310 remains in the OFF power state until a
Device Reset.
The DBE_VALID_DATA register is defined in Table 32.

requested. A value of A596h is required
to confirm valid data.
