1) the AN1x Reference Manual documents commands such as the one list 
above and 2) the OS update info was provided to me by a a Yamaha 
Customer Assistance tech during an email exchange prior to receiving 
the v1.04 EPROM update.

An intermittent clipping in the Sync Delay Effect and an 
erroneous 'low battery' warning message.

No.

Don't know - most likely they are calibration and self test routines 
used by qualified service technicians.  Play around with them at your 
own risk.
