#182640 - I guess a quite frequent oversight Responding to: ???'s previous message |
Maarten Brock said:4. CJNE also changes the carry, it is often used by SDCCYes I forgot about that one... :-(
I remember a loooong time ago when I were new to this processor, I skipped saving the CY (PSR) in an ISR that "did not change any flags". Of course the ISR had a CJNE and some quite interesting random occurences were seen. I'll never forgt that one again. Erik |
