Suppose I have clock 50 mhz and I want to generate a random number between
1 - 13 (inclusive both)
Suppose when I click a key, then I want a random number between 1 - 13 generated.
My idea:
Click Key
-> (take last 4 digits of clock MOD 13) + 1
I'm not sure how I can access the last four bits of the clock?
