Good info, but unfortunately it didn't work.
I just read the manual that you indicate and tested unfortunately
didn't work either, it look at the start to be the reason... :(
I performance the test refered on the manual, at first i did the set
on DIO12 pin as input ( by changing the address 0x8084 00014) and read
the memory address (0x8084 0004). I gotted 0xDB.
Then i connected ground signal on the pin and i red the memory address
and had no change on it. Still 0xDB.
So, i disconnect the ground signal and connect to 3,3V and red the
memory address and had no change on it again. Still 0xDB.
The DMA only "mess" with output pin setting so to speak, not with
input so it says on the manual...
My board is TS-7370 with EP9302 arm processor...
0x80804 0014 -> PBDDR address
0x80804 0004 -> PBDR address
I have used the simple functions to read and write the memory values
example:
(Check all pin are inputs.. 0 - Inputs)
>peek16 0x80840014
0x00
>peek16 0x80840004
0xDB
