CC1310: CC1310 Radio Single ended and Differential Mode

Harikrishnan R S

Part Number: CC1310

Hi,

 

I am currently using CC1310 SoC for development and I am having the following doubts.

There are 2 pins for transmission and reception in CC1310 as RFN and RFP which could be used in single ended mode (separately) and in differential mode. As I understand, the CMD_RADIO_SETUP is used for setting up these configurations.

In the CMD_RADIO_SETUP command, field frontEndMode is used for configuring the radio in below modes

0x00: Differential mode
0x01: Single-ended mode RFP
0x02: Single-ended mode RFN
0x05: Single-ended mode RFP with external
front-end control on RF pins (RFN and RXTX)
0x06: Single-ended mode RFN with external
front-end control on RF pins (RFP and RXTX)
Others: Reserved

  1. How could we configure one pin for TX and other one for RX ? (Let RFN be RX and RFP be TX).
  2. What will be the status of RFN/RFP when the other pin is used in single ended mode?

Thank you in advance for any help you provide.
