This one pulls another subroutine, which I have not had the patience to pull apart in understanding  Maybe you can have a look? |
Starting from scratch, got the Renesas 72531 manual, this stuff really makes my head hurt.
12FCC looks like a routine where eventually r0 gets tested and if:
0 - goes to 129C4 and loads FFF842A0 into r5
1 - goes to 12FF2 and loads FFF848FE into r5
2 - goes to 12FFE and loads FFF8490E into r6
result from subroutine gets returned in r2
I'll need a lot more time to learn how these things work...
Is there any way to trace RAM addresses from their map locations?
Code:
010E00: 000D0560 pointer to MAF scaling table info
0D0560: 00360000 ?2D table with 0x36 (54) values
0D0564: 0011FCD4 pointer to 54 MAF_Volt float values
0D0568: 0011FDAC pointer to 54 MAF_G/S float values
I couldn't find any references to 10E00, which I assume is indirectly referenced.
