The MCP2510 is a low pincount stand-alone CAN con-
troller which interfaces to a microcontroller via a stan-
dard Serial Peripheral Interface (SPI™).
The feature set of the MCP2510 makes it very versa-
tile. It would be impossible to document every way the
MCP2510 can be configured and used. Therefore, this
application note will provide examples and discussions
on some typical configurations.
This application note focuses on “using” the MCP2510
and sections include:
• Minimal configuration necessary to enable the
CAN node
• Features and how they may be implemented
• A detailed discussion of many of the registers
• Potential pitfalls during implementation AN739
An In-depth Look at the MCP2510

INTRODUCTION received messages. The code would be more opti-
