You should set your CONFIG parameters in your source code so that they
are conspicuous. Read the C compiler manual for information on setting
CONFIG bytes. It will be under the "#pragma CONFIG" heading.
1. Your clock frequency may be different than what you think it is.
2. I am going to guess that your WDT may be enabled which is causing the
reset.
