font-family:"Arial","sans-serif"'>Setting the OPT registers for ping and pong
to 0x20320002 and 0x20310002 should set CIPR to 2 and 1 when the transfers have
completed, I think. CIPR is actually getting set to 6 and 4 respectively,
and if I use 6 and 4 as my masks things seem to operate as expected (at least
ping and pong get updated and waitfordma() does not hang). To my
knowledge the OPT register is the only register that can effect the CIPR... so
this discrepancy is confusing to me. Any thoughts?</span><o:p></o:p></p>
