#101520 - restoring stack Responding to: ???'s previous message |
Oleg Sergeev said:
I use MOV SP,#(STACK-1) instead. By this way it is possible to jump to the beginning of main loop from any subroutines. ... which is - in a crude way - similar to the "try...catch"... I also think that there is a case when a jumpout from a called subroutine is justified: when such an exception occurs, which requires some operator intervention and results in some form of restart anyway. For example, if a checksum on critical parts of RAM fails, or contradictory inputs from sensors occur (indicating hardware failure and requiring immediate shutdown)... Jan Waclawek |
