DS80C410/DS80C411 Network Microcontrollers with Ethernet and CAN
Modification of the CAN registers located in MOVX memory is protected through the SWINT bit. Consult the
description of this bit in the High-Speed Microcontroller User’s Guide: Network Microcontroller Supplement for more
information. The CAN module contains a block of control/status/mask registers, 14 functionally identical message
centers, plus a 15th message center that is receive-only and incorporates a buffered FIFO. Table 18 describes the
organization of the message centers located in MOVX space.
