Hmm...it appears your vectors are mapped to RAM if your code's 
running from flash, or mapped to flash if you're running code from 
RAM. I haven't seen this done before.

(According to pg.42 of the 2106 UM for the Sys. control block)
MEMMAP = 1 (when in User Flash Mode)
MEMMAP = 2 (when in User Ram Mode) 

Try switching your MEMMAP assignments and see what happens.
