Suppose we want to use a timer to generate a PWM signal.
-PWM has a duty cycle of 25%.
-PWM has a fixed frequency of 320 Hz.
-The input clock to the timer is 32 MHz.
-The timer uses PWM mode 2: the output is high if the counter is larger than or equal to the content of CCR.
How would you design the prescaler (PSC), the auto-reload register (ARR), and the compare and capture (CCR)? Show your calculation.
