As far as i know the CCP is the same on most pics.... You need to change
the polirity of bit zero to sent the next edge Teh below is from a 16f1827
but i am pretty sure it works with a 690.

 banksel CCP4CON     ; bank 6
 btfsc CCP4CON,CCP4M0   ; check for channel or space
 goto DO_SPACE    ; mark / space switch

DO_MARK
 bsf  CCP4CON,CCP4M0   ; set for falling edge compare
......


DO_SPACE
 bcf  CCP4CON,CCP4M0   ; set for rising edge compare
