/**
* @name PWM configuration
*
* To find appriopate device and channel find in the MCU datasheet table
* concerning "Alternate function AF0 to AF7" a text similar to TIM[X]_CH[Y
],
* where:
* TIM[X] - is device,
* [Y] - describes used channel (indexed from 0), for example TIM2_CH1 is
* channel 0 in configuration structure (cc_chan - field),
* Port column in the table describes connected port.
*
* For Nucleo-L4R5ZI this information is in the datasheet, Table 16, page
* 117.
