I checked the routine again.
The semaphore is the "lock" variable.
- either set to 0x80 by TAS at the beginning of the critical section
- either manually reset to 0 at the end of the critical section
The variable can't have any other value.
So in this case, BSET.B #7 is equivalent to TAS.
I still believe that my patch is correct (in this special case).
