TIM2 Configuration: Output Compare Toggle Mode:
To get TIM2 counter clock at 1 MHz, the prescaler is computed as follows:
Prescaler = (TIM2CLK / TIM2 counter clock) - 1
Prescaler = (SystemCoreClock /1000000) - 1
CC1 update rate = TIM2 counter clock / uhCCR1_Val
= 1 MHz/625 = 1600 Hz
==> So the TIM2 Channel 1 generates a periodic signal with a frequency equal
to 800 Hz.
CC2 update rate = TIM2 counter clock / uhCCR2_Val
= 1 MHz/1250 = 800 Hz
==> So the TIM2 Channel 2 generates a periodic signal with a frequency equal
to 400 Hz.
CC3 update rate = TIM2 counter clock / uhCCR3_Val
= 1 MHz/2500 = 400 Hz
==> So the TIM2 Channel 3 generates a periodic signal with a frequency equal
to 200 Hz.
CC4 update rate = TIM2 counter clock / uhCCR4_Val
= 1 MHz/5000 = 200 Hz
==> So the TIM2 Channel 4 generates a periodic signal with a frequency equal
to 100 Hz.
