I found this digging through my AE5R100V rom. It is used in a lot of places to switch between 2 different tables. At first it looked to me like it was related to what the current gear is and I thought maybe it was there to indicate if the trans was in 1st. But the more I look at where the result is used, the less that makes sense.
Here's the function:
Code:
bool __stdcall True/False_?(void)
bool r0:1 <RETURN>
True/False_? XREF[178]: 00014992(c), 00036f50(c),
00036fb4(*), 0003db30(c),
0003dc44(*), 0003e508(c),
0003e728(*), 0004000c(c),
00040158(*), 0004a554(c),
0004a5ac(*), 00058cae(c),
00058eec(*), 0005c8fc(c),
0005ca28(*), 0008da84(c),
0008dc8c(*), 000b5b3e(c),
000b5c0c(*), 000bd03c(c), [more]
00029904 D6 0D mov.l @(PTR_BOOL_0002993c,pc),r6 = ffff690f
00029906 60 60 mov.b @r6=>BOOL_ffff690f,r0 = FALSE
00029908 88 01 cmp/eq 1,r0
0002990a 00 0B rts
0002990c 00 29 _movt r0
-------------------------------------------------------------
The best I can tell, BOOL_ffff690f is written to from a function at 0002937c (AE5R100V) that is too long to post. I have attached the .bin if anyone wants to take a look.
