#90374 - DS1337 alarms Responding to: ???'s previous message |
Dear Craig.....
Calm down...I'm sure that you're not stupid...but such a nervous !!!. I cant understand ...why ???? you want to disable alarms but you wont to disable A2IE/A1IE in the status register.....which is your problem, if in the status register, the bits, A1F and A2F, are in "1" ...just only write "0" to these if you wont...no alarms at all. Or never read it's. If your micro's code is watching to the "time"...why to give some importance to the alarm output interrupt if you wont alarm, in some cases. I think that datasheet is refering to "disable an alarm" just deactivating A2IE/A1IE bits. Cant found anymore reading it. Why to set alarms time...if you wont to use it in some cases ?? Initial state (after power on) will never activate A1F/A2F bits. Is this correct ? or I can't understand your question. Best Regards. |
