5.3 Configuration of the UART

Programming the serial flash device through the CC313x UART interface requires the use of the following CC313x pins:

  • 55 – UART TX
  • 57 – UART RX
  • 32 – nRESET or 2 – nHIB

The UART TX and RX pins are used for data transfer. RTS and CTS signals are not used. The nRESET pin is used to reset the device. The UART data transfer occurs at 921600 bps.

The UART configuration is as follows:

  • Baud rate: 921600
  • Data bits: 8 bits
  • Flow control: None
  • Parity: None
  • Stop bits: 1
  • Polarity: Positive

The CMOS logic level specifications for the UART can be found in the Electrical Characteristics of the CC3135 SimpleLink™ Wi-Fi® Dual-Band Network Processor, solution for MCU applications Data Sheet or the CC3130 SimpleLink™ Wi-Fi® Wireless Network Processor with Coexistence for MCU Applications Data Sheet.
