CC2541: UART with power management

Part Number: CC2541

Hi Team,

I know we have the below two ways of using UART :

  • UART (without power management): there is no handshaking needed as the device is not going to sleep. Therefore, only the Tx and Rx lines are needed.
  • UART (with power management): using CTS/RTS handshaking to control sleep.

Here comes the question: Do we have a method that uses UART in Power Saving Mode and without CTS/RTS?  

Best regards,
Viki Shi
