PIC 16F1503 - change the frequency of internal iscillatoroscillator

My configuration bits are as follows:

#include <P16F1503.inc> 
__CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_OFF & _PWRTE_ON & _MCLRE_OFF & _CP_OFF & _BOREN_OFF & _CLKOUTEN_OFF
__CONFIG _CONFIG2, _WRT_OFF & _STVREN_OFF & _LVP_OFF

The relevant part of code I am using for changing the frequency is this:

banksel OSCCON
movlw   b'01101000'     ; Int. osc. 4 MHz
movwf   OSCCON
btfss   OSCSTAT, HFIOFR ; Is internal oscillator running?
goto    $-1             ; No, loop one line back...
btfss   OSCSTAT, HFIOFS ; Is internal oscillator stable?
goto    $-1             ; No, loop one line back...

My debug tool is unfortunately just simulator. The problem is, that execution never reachreaches the breakpoint on line 192: 

enter image description here

So this means, that internal oscillator never gets stable?

I am using:

  • IDE: MPLAB X IDE v1.20
  • Compiler: MPASM v5.45

What am I doing wrong?
