Pulse width modulation mode allows you to generate a signal with a frequency determined

by the value of the TIMx_ARR register and a duty cycle determined by the value of the
|
||||
TIMx_CCRx register.
|
||||
|
||||
The PWM mode can be selected independently on each channel (one PWM per OCx
|
||||
output) by writing 110 (PWM mode 1) or ‘111 (PWM mode 2) in the OCxM bits in the
|
||||
TIMx_CCMRx register. You must enable the corresponding preload register by setting the
|
||||
OCxPE bit in the TIMx_CCMRx register, and eventually the auto-reload preload register by
|
||||
setting the ARPE bit in the TIMx_CR1 register.
