'update CCPR1'

I am generating a square wave with TIMER1 and CCP Prescaler(in compare
mode).
I now want to increase the frequency every 1ms in order to sweep from one
frequency to another. How should I handle the updating of CCPR1H and
CCPR1L.

I recall an App Note on the PWM which dealt with updating the timer properly.
