Write register values in code

How can I directly write a register value in my code?

For example the PWM_CMR_CPOL (0x1u << 9) change the register value 0 to 1.

// This doesn't work
#define PWM_CMR_CPOL 1;

That won’t work. #define works like a placeholder everywhere the compilers find the term PWM_CMR_CPOL he would replace it with a 1.

Something like this should set the register Value to a 1

PWM->PWM_CMR = PWM_CMR_CPOL;

Thanks Markus_L811, that really helped me!

// solution of my problem was (don't forget the channel number!):
PWM->PWM_CH_NUM[6].PWM_CMR |= PWM_CMR_CPOL;
PWM->PWM_CH_NUM[6].PWM_CMR |= (1 << 9);                // or this

// simple test for printing the register values:
void test() {
    uint32_t registervalues;
    registervalues = PWM->PWM_CH_NUM[6].PWM_CMR;
    Serial.println(registervalues,BIN);                                   
    delay(1000);
 }

// look in the header files for register names, in my case: component_pwm.h  and instance_pwm.h

Good, but sorry really missed the channelname.
