if bus clock is 16 MHz, what is lowest and highest clock frequency that PWM Module can use?
Homework Answers
The maximum clock frequency that PWM Module can generate is equal to the bus clock frequency.So in the present case this will be 16MHz.
The minimum frequency depends on what is the largest value of PWM scaler that the PWM module can provide.
For example, for HCS12 PWM hardware module the maximum value of PWM scaler is 512 so the minimum frequency used by PWM is 16MHz/512 = 31.25 kHz.

2) (10 points) Consider a microprocessor driven by an 8-MHz input clock, with a 16-bit external data bus. Assume that this microprocessor has a bus cycle whose minimum duration equals 4 input clock cycles. A bus cycle is the number of clock cycles required to accomplish a task (such as data transfer). What is the maximum data transfer rate across the bus that this microprocessor can sustain, in bytes?

(3 points) The clock on the Basys-3 board is 100 MHz, so it has a 10 ns period (the time from the rising edge of one clock cycle to the next is 10 ns). For a 3-bit counter there are 8 clock cycles from the rising edge of one roll signal to the next. Therefore, the period of the roll signal is 80 ns and the frequency is 12.5 MHz.
