To generate a time delay of 0.2ms with a 1MHz crystal oscillator (XTAL), we need to calculate the Output Compare Register (OCR0) value.

Here are the steps:

1. First, we need to calculate the number of clock cycles needed for the 0.2ms delay. Since the clock frequency is 1MHz, the time period of one clock cycle is 1/1MHz = 1us.

2. To get a delay of 0.2ms, we need 0.2ms / 1us = 200 clock cycles.

3. In CTC mode, the counter counts up to the value in the OCR0 register, then resets to zero. So, we need to set OCR0 to the number of clock cycles we need - 1 (since the count starts from zero).

4. Therefore, the OCR0 value should be 200 - 1 = 199.

So, to generate a time delay of 0.2ms with a 1MHz crystal oscillator, the OCR0 value should be set to 199.

Assume that XTAL = 1MHz. Find the OCR0 value needed to generate time delay of 0.2ms. Use CTC Mode and no prescalar.
