RDOOLV BIT OPERATION:

Anomolous operation of the RDOOLV bit (Register 0x07, bit 3 on page 50 of
the Issue 6 datasheet) has been noticed. Under certain circumstances, the
RDOOLV bit may falsely indicate data out of lock.

It is recommended that spurious RDOOLV indications be ignored, and that
the RDOOLE bit (Register 0x07, bit 1 on page 50 of the Issue 6 datasheet)
be programmed to '0' in order to permanently disable RDOOLV interrupts.

The RDOOLV bit should only be examined as a diagnostic aid in situations
where other major on-chip alarms are indicated.

Note: The anomolous RDOOLV only occurs in revisions prior to 'Revision D'
of the PM5346 S/UNI-155 LITE. Subsequent revisions, starting with
'Revision D' have this problem corrected. Software work-arounds as
indicated above will work with all revisions. For details on identifying the
device revision, please refer to the Branding Diagram.
