I recently finished making a Minesweeper program for MirageOS and I was wondering how I could keep track of time. I know there must be some sort of hardware clock; how do I use it? Or at least is there an assembly routine that will allow me to read it?

I was designing a modular program executor when I encountered this problem: The code I was trying to execute was not being executed and instead the calculator reset. I've tried and checked everything; I think the problem is the address. Knowing the TI-84+ only has 24KiB RAM, it puzzled me to learn my program was using memory pointers all the way up to DFFF. Everywhere I have tried to execute has an address somewhere between 8000-BFFF. A brief summary of my test code is printed below.

Code: [Select]
Note: I know 0xC9 is the assembly equivalent of Return.

If I were to try this with the program data itself or a safe zone (like L1) it works just fine.
Displaying the memory pointer just before calling it shows something like C3F2 or D19A.

My questions are, how is this caused, and how do I work around it?
