Nuvoton/Winbond !SD17xxx chipcorder looping

Having had my emails ignored and being unable to find intelligent life
in the Winbond/Nuvoton phone system - is it possible to do automatic
power up message looping with the new ISD17xxx series of chipcorders
ie apply power and the chip plays the single recorded message (which
may not occupy the entire memory space) seamlessly forever (or until
the power is removed).
cheers, m
