24.4.2 Synchronous Client Mode

The following bits are used to configure the EUSART for synchronous client operation:

  • SYNC = 1 (configures the EUSART for synchronous operation)
  • CSRC = 0 (configures the EUSART as a client)
  • SREN = 0 (for transmit); SREN = 1 (for single byte receive)
  • CREN = 0 (for transmit); CREN = 1 (recommended setting for continuous receive)
  • SPEN = 1 (enables the EUSART)
Important: Clearing the SREN and CREN bits ensure that the device is in Transmit mode, otherwise the device will be configured to receive.
