Figure 4.15 RS232 Port
MYB-Y6ULX is equipped with an RS485 interface with electrical isolation. This function is
connected to the UART4 controller on the processor. Sending or receiving is controlled by
a GPIO. The UART controller supports 7 bit or 8 bit data bits, 1 or 2 stop bits, and
programmable parity. The chip of the transceiver is ISO3802 from TI, for more details
about the ISO3802 chip, please see its datasheet.
Please refer to the schematic of the RS485 below for detail.

4.2.11 CAN
A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to
allow microcontrollers and devices to communicate with each other in applications without
a host computer. It meets the specific requirements of the field, such as real-time
processing, electromagnetic interference (EMI), the environment reliable work,
cost-effective and the bandwidth requirements.
The processor has two CAN bus controllers, has a complete CAN protocol version 2.0B
