a. Maximum CPU frequency is 12 MHz at 3.3V. With the CPU clock divider set to 1, the external clock must adhere
b. If the frequency of the external clock is greater than 12 MHz, the CPU clock divider must be set to 2 or greater. In
to the maximum frequency and duty cycle requirements.
this case, the CPU clock divider will ensure that the fifty percent duty cycle requirement is met.
