CC1120: CC1120 EXTENDED ADDRESS Write/Read Problem

Hi Experts,

I got a problem to control CC1120 by using STM32 LL_Driver

According to CC1120 User guide (Figure 1) I know that to write data to the register located at the extended address, add +0x00 to 0x2F, enter the address of the extended register, and then enter the value of what I write to the register

- Figure 1

For example ) There is a case where I want to write 0x01 to the FREQ0 register(0x0E) located at the extended address. 

In that case, I transmitted the packet as shown in Figure2 to CC1120 using STM32 to SPI Interface

- Figure 2

It  was confirmed that the above method works when applied to the STM32 HAL_Driver. (By read Partnumber)

However when using LL_Driver, that method did not work.

This is my question, 

1. Is the packet written to the extended register correct?

2. I Attach the LL_Driver Function that I wrote. Thank you for check the code

<LL_Driver code>

void Extend_Resgister_write(uint8_t action_byte, uint8_t register_byte, uint8_t extend_register_byte, uint8_t value_byte)
{
int i=0;

uint8_t TX_Data[4] = {0,};

//uint8_t RX_Data[4] = {0,};

TX_Data[0] = action_byte|register_byte;

TX_Data[1] = extend_register_byte;

TX_Data[2] = value_byte;

LL_GPIO_ResetOutputPin(CS_GPIO_Port, CS_Pin);

for(i=0;i<4;i++)
{
while(!LL_SPI_IsActiveFlag_TXE(SPI1)) {}
LL_SPI_TransmitData8(SPI1, TX_Data[i]);
}

LL_GPIO_SetOutputPin(CS_GPIO_Port, CS_Pin);
}

Looking forward to your advice. Thank you.

Kind regards,
