3.4.7. CAN Interface
*
In the case of multiplexing, the module provides 1 CAN interface which is compliant with the CAN 2.0B
specification. It can be configured to meet the specification of CAN with flexible data rate CAN-FD. CAN
2.0 carries a data payload up to 8 bytes and CAN-FD up to 64 bytes.

3.4.8. LCM Interface
In the case of multiplexing, the module supports an LCD-TFT display controller capable of providing a
16-bit parallel digital RGB (Red, Green, Blue) or an 8-bit I8080 interface. The controller supports
conversion from YUV420 to RGB565 in RGB display.
