MCP2510
Only messages that have not already begun to be
transmitted can be aborted. Once a message has
begun transmission, it will not be possible for the user
to reset the TXBnCTRL.TXREQ bit. After transmission

DS21291F-page 16
The CANINTE.TXnIE bit
determines if an interrupt
should be generated when
a message is successfully
transmitted.
