and whenever you use interrupts that tranfer data to the rest of the code, otherwise you risk the shared data problem.
If you know what is going on (e.g. an int is more than a byte) there is nothing keeping you from using C in the above case. saveEA = EA; EA = 0; .... EA = saveEA; is perfectly valid in '51 C. Erik |
