I wish to read the odd 8bit registers must I always read the even then use the
upper 8bits since I can't address the next
byte directly?

 

No, you do not have to access 16-bits and then ignore 8-bits when accessing
locations in asynchronous memory. The EBIU has
byte select lines /ABE1 and /ABE0 that allow you to fetch and modify bytes in
asynch memory. This is described in page 16-22 of the latest 561 Blackfin
hardware reference manual.
