timer 16 has hang or stop working for 1 sec.

Hi , I am using stm32f030f4p6tr in TSSOP20 package. My configuration is as follow:

1. keil MDK 5

2. cube mx

3. GPIO PIN PA2, PA1, PA7, PA9, PA10 and PB1.

4. Timer 16 used with interrupt global interrupt.

5. Timer 3 with output compare no output mode

6. Timer 14 and timer 17 for PWM generation.

Problem is that timer 16 has hang or stop working for 1 sec.

By using six GPIO I am generating some sequence. At every timer interrupt occurred the sequence changes. The frequency is generated by this sequence I want to change frequency linearly from 5 Hz to 294 Hz . For changing this frequency of sequence I am using TIMER 3 in output compare no output mode. I was checking timer 3 counter value and after the 10000 count of timer 3 the htim16.Init.Period changes.

This is works but after some changing frequency the timer 16 hang for sec. I didn’t understand what happen. I think there  is conflict between timer 16 or timer 3.

Please help me.
