#zero_ram zeroes after reset_cpu()?

Does the #zero_ram directive cause RAM to be zeroed whenever the program restarts? Does it zero RAM after a call to reset_cpu()?

Think about it. If the program counter starts back at 0 then wouldn't it execute those instructions again.

On one project, I actually wrote my own routine to zero the ram because I needed to save the data on certain resets to the CPU. CCS doesn't allow you to control when this zeroing occurs.
