TPS929120-Q1: After eeprom programing stoped responding

Hello

I have issue with my tps929120 on your evalboard.

TPS929120 stoped responding after I tried to made eeprom programing

I wrote function as below

void Unlock_EEPROM_TPS(uint8_t adress)
{
    uint8_t temp1, temp2;

    temp1=Read_data_TPS(adress, CONF_EEPMODE);
    temp2=Read_data_TPS(adress, CONF_STAYINEEP);

  
    Write_data_TPS(adress, CONF_EEPGATE, 0x00);
    Write_data_TPS(adress, CONF_EEPGATE, 0x02);
    Write_data_TPS(adress, CONF_EEPGATE, 0x01);
    Write_data_TPS(adress, CONF_EEPGATE, 0x09);
    Write_data_TPS(adress, CONF_EEPGATE, 0x02);
    Write_data_TPS(adress, CONF_EEPGATE, 0x09);

    Write_data_TPS(adress, CONF_EEPMODE, temp1|0x01);
    Write_data_TPS(adress, CONF_STAYINEEP, temp2|0x80);

}


void Write_EEPROM_TPS(uint8_t adress)
{
    uint8_t temp;

    temp=Read_data_TPS(adress, CONF_EEPPROG);
    Write_data_TPS(adress, CONF_EEPPROG, temp | 0x04);

    delaymsTPS(300);
}


void Lock_EEPROM_TPS(uint8_t adress)
{
    uint8_t temp=Read_data_TPS(adress, CONF_STAYINEEP);
    Write_data_TPS(adress, CONF_STAYINEEP, temp&(~0x80));
}


void EEPROM_FAIL_STATE(uint8_t adress, uint16_t FS0, uint16_t FS1)
{
    Write_data_TPS(adress, 0xC0, (uint8_t)FS0);
    Write_data_TPS(adress, 0xC1, (uint8_t)(FS0>>8));
    Write_data_TPS(adress, 0xC2, (uint8_t)FS1);
    Write_data_TPS(adress, 0xC3, (uint8_t)(FS1>>8));
}

In main function I call this function like below:

               
                        ConFSMode eepstruct;
                         Unlock_EEPROM_TPS(0x00);
                         TIMERUS=2000;
                         while(TIMERUS);
                         EEPROM_FAIL_STATE(0x00, 0xff0, 0xff);

                         for(int i=0; i<12; i++)
                         {
                            if(i%2) eepstruct.EEPI=63; else eepstruct.EEPI=10;
                            eepstruct.OUT=i;
                            TPS_EEP_Setup(0x00, &eepstruct);
                         }
                         TIMERUS=2000;
                                                 while(TIMERUS);
                         Write_EEPROM_TPS(0x00);
                         TIMERUS=2000;
                                                 while(TIMERUS);

                                                 Lock_EEPROM_TPS(0x00);

                         TPS_Force_FS(0x00);
                        

                         while(1);

And after turn off power supply and turn on tps stopped responding.

Did i damage IC and now i have to soldered new TPS929120 or it is  some way to trying reset tps.

I will be glad for respond.

Thank you in advance
