Paste the code that references the word at 8f8d6.

Paste the code that show sjmp to 8FB39 is a valid destination.

Cross post with yours, but still valid.
Suss, sorry aussie slang.

What do you think of this?

Well, after removing the SCA 8f8d8 and carefully going through the code, I found several references to the word 115a or address 1115a rather. But it looks to me like the ad call is for ldzbw and the 08 would make whatever the ad was pointing to =8. So now I am a bit confused. So it does somewhat look like code but not complete code.

the 8f951 to 8f956 looks to be fill to me. or an address pointing to zero

[BOOSTEDEVERYTHING]

The other thing that confuses me is that there doesnt seem to be anything to start the next subroutine....

Code: Select all

8f8d5: f0                 ret                    return;

8f8d6: ad,08              word    8ad
8f8d8: ad,08              word    8ad
8f8da: 5a,11              word   115a
8f8dc: b8,22              word   22b8
8f8de: 5a,11              word   115a

>>>>>>>> Seems like ther should be a push command or other Subroutine "starter" command, seems to start mid-routine

8f8e0: 5a,11,00,00        sb3b  R0,R0,[R10++]    R0 = [HSO_IntPend1];

Sorry, This is after adding a word command to the dir file for 8f8d6 8f8de, Also there are no calls to 8f8e0

8f8e6: a1,40,0f,36        ldw   R36,f40          R36 = f40;

But there are calls to Sub_8f8e6
But I do not understand the repetitive words, the 115a and 8ad if the above are words, So some of it must be code, Correct?

Sorry, This is after adding a word command to the dir file for 8f8d6 8f8de

Not sure what you are referring to as the next subroutine.
No worries adding the word command to visualise what is going on.
To me, the part that is still commanded with a scan as code stands out like a sore thumb as part of the word/structure.

Looking at that part without any commands, a pattern is evident.
Find the code referencing the word 8f8d6 and paste it up here.

Code: Select all

8f8d6: ad,08              word    8ad

8f8d8: ad,08,5a,11        ???   

8f8dc: b8,22              word   22b8

8f8de: 5a,11,5a,11,00,00,5a,11  ???  

>>>>>>>> Seems like ther should be a push command or other Subroutine "starter" command, seems to start mid-routine

There can be code stubs, but treating them with great suspicion is the correct approach. More likely to be something else.

[jsa]

But there are calls to Sub_8f8e6

Cross post again, so continuing from my previous.

Good, makes it clear cut as code.

But I do not understand the repetitive words, the 115a and 8ad if the above are words, So some of it must be code, Correct?

Prove it one way or the other, post up the code referencing 8f8d6, we can sift through it.

Have you read about the address modes, was there mention of word alignment?

In the context of word alignment what has the FF fill done?

SAD has picked up 8f952 and 8f954 as words.
Have you searched for code referencing 8F952?
Could 8F956 be part of the same word/structure?
