Are you referring to the "RF (command) Strobe" register in section 23.3.1.2 in www.ti.com/.../swru283b.pdf

Hi Tom

I know that this documents explain it. But my customer would like to know "the case/condition that the "RFST" will not be the value of "0"".

Best regards.

Hi Tom,

I know that the RFST register is cleared (set to 0x00) when the radio is ready for a new command.
If this register will not be cleared, what is the case you think?

Best regards.

When sending an link layer engine command to RFST (that is, a command where bit 7 is 0), RFST will retain that value until the command has been received by the link layer engine. RFST will not go back to 0 if you try to send a command while the link layer engine is not enabled, that is, LLECTRL = 0. I am not aware of any other cases where RFST will be stuck.
