Hi community member,
Please let me confirm the following question.
[Question]
Can customer use the burst register access mode for one register writing/reading?
**Of course, they will release the nCS pin after the each writing/reading operation by MCU.
If there is any problem for this, please show us the reason.
If you have any questions, please le me know.
Best regards.

Hi
The code examples for CC112x also use burst access and this works fine. Below is a plot from the manual calibration routine where I read the FS_CAL2 register using a burst access.
Hi Siri,
I got the waveform of SPI from my customer.
Please see it.
Also, please let me confirm the following question.
When we send the writing commnad to CC1121 like FS_CAL2 or FS_VCO2, Cmd Strb, the SO pin output the 0x0F.
* I also attached this power point file as below.
Confirm the behavior on my hands.pptx
Is this behavior any problem?
If you have any questions, please let me know.
Best reagrds.

Which data did you see??
If you pointed out the result on power point, the CC1121 works well.
But in case of the picture as below, this is not worked fine.
Best regards,
Kaka
The first byte return on the SO line when writing to FS_VCO2 indicates that the radio is not in IDLE mode when you are doing this. Please make sure to not modify these register unless the radio in in IDLE state. Also make sure that both the RX FIFO and the TX FIFO is empty. Then the status should return 0c0F when the read/write bit is 0 and 0x00 when the read/write bit is 1.
