#188542 - Maximum possible delay using a Timer
A timer keeps incrementing itself after every 12 oscillator cycles. So for a 12 MHz crystal it would have incremented 1 million times in a second.

Here's my question. Suppose I'm using Timer 0 as a 16 bit timer, the maximum value it can take attain is 65536 (2^16). And it takes 65. 536 ms (65/1M) to attain this value.

So what if was want to generate a delay that's greater than 65 ms? Do I have to wait for it to overflow and then start it all over again?
