RC circuit Design
When the frequency of operation is variable, and you nead at least 11 clock cycles, you need to calculate your RC delay time based on the lowest frequency. I also assume that the RC time may/can be longer.
Is this a power up delay, or reset given from another circuit?
for a decision level of half the supply voltage:
Delay (rising voltage, from empty capacitor to supply voltage) = 0.69RC.
Maybe you can supply some additional info to be sure our comment is useful to you.
