#90082 - Re:initializing SP to 7FH Responding to: ???'s previous message |
It is good idea
Why? Because In one of my projects 108 lower bytes of ram was used and i had 43 flag and 2 interrupts, when external interrupt occurred some flag damaged. And after any external interrupt,the program had to started from specific point for this reason at first of interrupt routine i write #9 to stack for preventing of more stack increase somebody said this metod is nasty and sludgy! So,I think this idea is good for stack space |

| well | 01/01/70 00:00 | |
| well well | 01/01/70 00:00 | |
| well, well - done | 01/01/70 00:00 | |
| tight SRAM - use C | 01/01/70 00:00 | |
- or assembler | 01/01/70 00:00 | |

| very old assemblers only | 01/01/70 00:00 | |
| Let the assembler do the work! | 01/01/70 00:00 |
