Sercom configuration

Select data frame configuration for serial communication universal synchronous/asynchronous receiver/transmitter (SERCOM USART) on Arduino SAM D21 core boards

Since R2026a

Model Configuration Pane: Hardware Implementation / Hardware board settings / Target hardware resources / Sercom properties

Description

Select the data frame configuration for the SERCOM USART communication. Settings are in the form SERIAL_nXm. The first digit n indicates the number of bits in each data packet. The letter X indicates the parity bits present in the data packet. The second digit m indicates the number of stop bits in each data packet. For example,

  • SERIAL_8N1 indicates 8-bit data communication with no parity bits and one stop bit

  • SERIAL_5E1 indicates 5-bit data communication with even parity bits and one stop bit

  • SERIAL_6O2 indicates 6-bit data communication with odd parity bits and two stop bits

The following table lists supported Arduino® SAM D21 boards and associated SERCOM channels.
