[ts-7000] TS7800 PC104 16 bit memory access problem

["tommessum" <>]

I cannot seem to be able to set the PC104 for 16 bit memory mapped bus access 
(only 8 bit)!  

I tried setting the base address for the mmap() fumction to both 0xED00_0000 
and 0xEC00_0000 as the manual says, but both give me 8 bit access!  

I know this by following the R/W and data line responses on a scope (i.e. two 
consecutive writes and reads)

I have also tried setting/clearing bit 11 of 0xE800_000C  (TS special ISA 
pinout enable), no effect.  

Is there something else I have missed? 


PS: yes, I have set port directions to ISA (rather than GPIO)
