I'm reading through Microchip's AN1171 (Touch switch setup), and one  
example for setting up Timer 2 (on a 16F with CapSense) shows this...

      T2CON = 0x04;     // T2ON, prescaler & postscaler = 1:1
      T2CON = 0x01;     // adjust prescaler
      PR2 = 0xB4;     // w/pres.1:1, 0xB4 sets 125us scan rate.
      TMR2IF = 0x00;
      TMR2IE = 0x01;
      ...

Is there a reason for the second line?  T2CON is set, then immediately  
changed again?  I figured I'd ask in case there's some errata I missed  
where perhaps the prescaler is supposed to be set to 1:1 while  
switching on T2, etc.  Or maybe this is some C-specific workaround?   
Or am I reading too far into what is really a typo?

Cheers,
-Neil.
