COMSTAT. In Mode 1 and 2, there are two interrupt

FIGURE 23-8:
23.15 CAN Interrupts
The module has several sources of interrupts. Each of
these interrupts can be individually enabled or
disabled. The PIR3 register contains interrupt flags.
The PIE3 register contains the enables for the 8 main
interrupts. A special set of read-only bits in the
CANSTAT register, the ICODE bits, can be used in
combination with a jump table for efficient handling of
interrupts.
All interrupts have one source, with the exception of the
error interrupt and buffer interrupts in Mode 1 and 2. Any
of the error interrupt sources can set the error interrupt
flag. The source of the error interrupt can be determined
by
enable/disable and flag bits – one for all transmit buffers
and the other for all receive buffers.

The interrupts can be broken up into two categories:
receive and transmit interrupts.
The receive related interrupts are:
• Receive Interrupts
• Wake-up Interrupt
• Receiver Overrun Interrupt
• Receiver Warning Interrupt
• Receiver Error-Passive Interrupt
The transmit related interrupts are:
• Transmit Interrupts
• Transmitter Warning Interrupt
• Transmitter Error-Passive Interrupt
• Bus-Off Interrupt
