Protocol Mode
=============

The SANPO protocol adds an interface number and data length around raw CAN,
CAN FD, or RS485 data. It is suitable for multi-channel CAN/CAN FD/RS485
control and for connecting a host controller through SPI.

- For SANPO USB to CAN FD, see :doc:`usb_fdcan`.
- For SANPO USB to RS485, see :doc:`usb_rs485`.
- For SPI to CAN, see :doc:`spi_can`.
- For SPI to CAN FD, see :doc:`spi_fdcan`.
- For SPI to RS485, see :doc:`spi_rs485`.
