I can`t to turn on a TA1 output in HRTIM.

[Andrew Androsow]

Hello! I am trying to start HRTIM TIMA in PWM mode. Clock frequency of HRTIM is 140MHz. I use CubeMX 5.1.0 , chip is STM32F334R8T7. The configuration of the timer is following: set source is timer period event, reset source is timer compare 1 event. Output is TA1.

In Main() function I tried to start the timer. At first, I switch on a bit in OENR register:

/******************************************/

 HRTIM1->sCommonRegs.OENR = HRTIM_OENR_TA1OEN;

/**************************/

After this, in register ODSR independetly appeared the bit TA1ODS... that inform, that output TA1 disable.... I don`t know, what to think..

Thaks greatly for replies!

P.S. The function of initialization is below:
