Hello, I am not able to persuade my RTC to generate periodic interrupts more frequent than 2Hz (that works just fine). In theory, the device should support 2, 16, 128 and 1024 Hz. When I run my program on the simulator, and I select any frequency above 2 Hz, the setting jumps back to "reserved". Did you ever encounter this problem? I still haven't tested this on the target - only the simulator.
I recommend that you test on live hardware. If the behaviour differs, then you might have found a bug in the simulator and can report that to Keil. Note that the simulator does not support all peripherials fully for all processors. Have you looked up your device on this site and checked what support Keil claims for your processor?
Thanks for your reply. It was, almost as usual, my fault...
