What did you use to make that assembler? It looks like it's been disassembled from something as it has generic labels.
In MPASM for a 16F chip for ex you would write:
Code:
__CONFIG CONFIG1, _WDT_OFF && _INTIO && _MCLRE_OFF && _LVP_OFF
This turns off watchdog, low voltage programming, and disables MCLR, it also sets the internal oscillator with OSC pins as IO.
The watchdog timer is a "failsafe" module built into most PIC chips, what it does is listen for a command called clearwdt, which is clear watch dog timer, if it does not get this command within the watchdog timeout period it will reset the processor, so in effect, if you never clear the WDT and dont switch it off your chip will be in a permanent reset cycle.
Much like if you didn't pull MCLR high.
