DESCRIPTION

Users can switch the communication mode via the MODE pin: high for SPI to CAN, low for UART to CAN.
In UART mode, the SPI interface is unavailable; similarly, in SPI mode, the UART interface cannot be used. In this case, the product can only function as an SPI slave.

When switching communication modes…
After changing the pin levels, it is necessary to pull the RST pin low to reset the product to activate the setting.
