21065L host interface EPBx access

With SHARC ADSP-21065L we are attempting to use the host interface with transfers through the EPBx buffers in single-word transfers as described in ADSP-21065L SHARC User’s manual ver. Sept. 8 1998 page’s 8-18 through 8-20. The transfers work, however we seem to have to do 8 accesses in order to read a single word. This does not seem correct. We should be able to get the data in one access. Can someone explain this or are we missing something. (As a side note perhaps someone could explain how a single transfer works with a six-deep FIFO).

Thank you.
