I Thank you all for your educative answer.

So if I understand correctly the calculation is like that
say I am using 32,768Khz crystal
1 / 32768 = 0.0000305
0.0000305 * 4 = 0.000122sec

and if I use 4Mhz crystal
1 / 4,000,000 = 0.00000025 * 4 = 0.000001sec

am I right?

Using a 32.768kHz crystal, which has an instruction time of

1000000 / (32768 / 4) = 122us
