Can you please help me with the instructions that are used to generate 2 alternating pulses at 0.5 duty cycle whilst the pic is executing sinusoidal pwm using PIC 16F877 OR 16F887 IN ASM OR MICROBASIC.I need the pulses at 200khz.

Draw a timing diagram of what you require. It sounds like a divide-by-two flip-flop might do it, but I dont get your requirement?

Is the 200kHz signal related to the PWM signal?

yes it is a pwm signal .I have managed to use the ccp module to produce a sinusoidal pwm but i'm failing to incorporate the program to produce other two pulses of 0.5 duty cycle.
