BF52x HOST DMA issue

Hi dear Analog!


I need your help!


I try to organize infinite data read cycles in autobuffer mode via HOSTDP from BF522 slave processors to  BF523 master processor.  And when I try to process "Host read done" interrupt in slave processors I can't clear it by setting HOSTRD_DONE bit in HOST_STATUS register, but only by set DMA_CMPLT bit, which automatically break my infinit read cycles... Where can I read more about autobuffer programming model of HOSTDP??
