Simulating a routine that uses timer1 of 16F873 I meet an bad behavior.

      movlw   B'00000100'
      movwf   T1CON
      clrf    TMR1H
      clrf    TMR1L
      bsf     T1CON,TMR1ON     
      bsf     STATUS,RP0
      bsf     PIE1,TMR1IE
      bcf     STATUS,RP0
      bcf     PIR1,TMR1IF
      bsf     INTCON,PEIE
      bsf     INTCON,GIE
      btfss   INTCON,GIE
      goto    $ - 2
      ...
      ...
      bcf     T1CON,TMR1ON
      movf    TMR1H,W
      movwf   RegM
      movf    TMR1L,W
      movwf   RegL
      clrf    TMR1H
      clrf    TMR1L
      bsf     T1CON,TMR1ON

I turn off the TMR1, save the current count, erase the registers 
TMR1H:TMR1L and turn on the count...
but, hoo..return the previous values to the registers TMR1H:TMR1L.
I have tried in MPLAB and this does not happen.
