receives data, it is immediately sent to the other side bus without any processing. See section 3.3.1 for a
detailed description of this method.
Transparent conversion with identification is derived from transparent conversion, which means that the
serial frames sent or received contain valid CAN frame ID bytes. See section 3.3.2 for a detailed description of
this method.
Custom protocol conversion, serial frames must conform to the specified frame format. The valid serial
frame consists of frame header, frame length, frame type, frame ID, data field and frame trailer. See section
3.3.3 for a detailed description of this method.
2. Change direction
Change direction, which refers to the allowed direction of data conversion. TD5(3)USPCAN has three
conversion directions: bidirectional, only UART/SPI to CAN, only CAN to UART/SPI.
3. CAN frame information is allowed to be converted into serial frames
This configuration parameter is only valid in transparent conversion mode. If enabled, when CAN is
converted to UART/SPI, the frame information of CAN frame will be converted to UART/SPI at the same time.
See for details Section 3.3.1.
4. Allows the CAN frame ID to be converted into a serial frame
This configuration parameter is only valid in transparent conversion mode. If it is enabled, the frame
information conversion will be enabled by default. When CAN is converted to UART/SPI, the frame ID and
frame information of CAN frame will be converted to UART/SPI at the same time. See section 3.3.1 for details.
5. Position of CAN identifier in serial frame
This configuration parameter is only valid in the transparent conversion with identification mode,
including the setting of the starting address and length of the CAN identifier. See section 3.3.2 for details.
6. Frame header, frame trailer
This configuration parameter is only valid in the custom protocol conversion mode, and is used to set the
frame start and frame end of serial frames.
4.1.2 UART parameters
1. Baud rate
Refers to the working baud rate of serial port. The effective baud rate of serial port is shown in Table 4.6.
2.Frame interval
Refers to the time interval between UART communication frames. See the definition of UART frames in
section 3.2.2 for details.
