How to Set 200Hz PWM Output on ATMEL Attiny861 at 1MHz Clock Frequency?

Please i need your help and support in correcting this code. I am using attiny861 to generate a
PWM Signal of 200Hz.The codes below are what i wrote to generate the signal
but when i checked the frequency of the signal on the oscilloscope,I got 7.396kHz instead of 200Hz.
According to the datasheet the PWM Frequency is calcualted with this equation:

PWM(freq.) = Fclk/N where N is the TOP value.My microcontroller is
running @ 1MHz.
I would be glad if somebody could put me through on how to get the desired frequency.Thank you for the usual support.Best regards.


Code:



#include
#include
#include
#include "NewHeaven_LCD.h"


int main( void )
{
int LED_Power=1;
int On_Time=0;


// Set PWM-Port PB4
PORTB = 0x00;
DDRB |=(1

Do you want to put out a 200 Hz since wave as PWM or want a PWM signal that has a frequency of 200 Hz? For the latter you need to determine the duty-cycle and use that along with the time period of a 200 Hz wave to compute the on and off times.

T = 1/200
Duty cycle (d) = 50% (at idle)
Ton = T * d
Toff = T - Ton

# Set output low
# Set output high
# wait for a delay of Ton
# Go to 1
