Can't get HSIRDY flag raised

Hello! I'm trying to configure TIM1 in encoder mode programming on bare metal. But problem comes up when I try to enable the HSI: the clock is enabled but it doesn't get ready. I use the #include "iostm8s003f3.h" library.

void clock_config(void){

clock_init();

CLK_ICKR_bit.HSIEN = 0x01;

while(!CLK_ICKR_bit.HSIRDY); // program gets stuck here

.

.

.

}

But when I use StdPeriph, HSIRDY rises right after I run the debug mode. Library #include "stm8s.h" 

void clock_setup(void)

{

    CLK_DeInit();

    CLK_HSECmd(DISABLE);

    CLK_LSICmd(DISABLE);

    CLK_HSICmd(ENABLE);

    while(CLK_GetFlagStatus(CLK_FLAG_HSIRDY) == 0);

.

.

.

}

I tried to compare my code with the one that is used by STP lib and and everything looks similar. What could be missing?
