1. A 4.0 MHz clock signal is connected to the inputs of a 12-bit and a 16-bit counter. Each starts counting from zero. How long does it take before each reaches its maximum value?
2. A 10-bit counter, clocked with an input frequency of 512 kHz, runs continuously. Every time it overflows, it generates an interrupt. What is the frequency of that interrupt stream?
3. What is the purpose of the mbed's Real Time Clock? Give an example of when it might be used.
