Implementation notes:
|
||||
|
||||
CONDES routines with a type code of 2 are used to implement interrupt
|
||||
handlers. Note that these are called as soon as the program is started,
|
||||
so they have to cope with this. The indirect segment is set to the
|
||||
system bank when calling interrupt routines, this must must not be changed
|
||||
when returning.
