23.15.1
To simplify the interrupt handling process in user firm-
ware, the ECAN module encodes a special set of bits. In
Mode 0, these bits are ICODE<3:1> in the CANSTAT
register. In Mode 1 and 2, these bits are EICODE<4:0> in
the CANSTAT register. Interrupts are internally prioritized
such that the higher priority interrupts are assigned lower
values. Once the highest priority interrupt condition has
been cleared, the code for the next highest priority inter-
rupt that is pending (if any) will be reflected by the ICODE
bits (see Table 23-5). Note that only those interrupt
sources that have their associated interrupt enable bit set
will be reflected in the ICODE bits.
In Mode 2, when a receive message interrupt occurs,
the EICODE bits will always consist of ‘10000’. User
firmware may use FIFO Pointer bits to actually access
the next available buffer.
23.15.2
When the transmit interrupt is enabled, an interrupt will
be generated when the associated transmit buffer
becomes empty and is ready to be loaded with a new
message. In Mode 0, there are separate interrupt
enable/disable and flag bits for each of the three dedi-
cated transmit buffers. The TXBnIF bit will be set to indi-
cate the source of the interrupt. The interrupt is cleared
by the MCU, resetting the TXBnIF bit to a ‘0’. In Mode 1
and 2, all transmit buffers share one interrupt enable/
disable bit and one flag bit. In Mode 1 and 2, TXBnIE in
PIE3 and TXBnIF in PIR3 indicate when a transmit
buffer has completed transmission of its message. TXB-
nIF, TXBnIE and TXBnIP in PIR3, PIE3 and IPR3,
respectively, are not used in Mode 1 and 2. Individual
transmit buffer interrupts can be enabled or disabled by
setting or clearing TXBIE and BIE0 register bits. When a
shared interrupt occurs, user firmware must poll the
TXREQ bit of all transmit buffers to detect the source of
interrupt.
23.15.3
When the receive interrupt is enabled, an interrupt will
be generated when a message has been successfully
received and loaded into the associated receive buffer.
This interrupt is activated immediately after receiving
the End-Of-Frame (EOF) field.

PIC18F2682/2685/4682/4685
In Mode 0, the RXBnIF bit is set to indicate the source
of the interrupt. The interrupt is cleared by the MCU,
resetting the RXBnIF bit to a ‘0’.
In Mode 1 and 2, all receive buffers share RXBIE,
RXBIF and RXBIP in PIE3, PIR3 and IPR3, respec-
tively. Bits RXBnIE, RXBnIF and RXBnIP are not used.
Individual receive buffer interrupts can be controlled by
the TXBIE and BIE0 registers. In Mode 1, when a
shared receive interrupt occurs, user firmware must
poll the RXFUL bit of each receive buffer to detect the
source of interrupt. In Mode 2, a receive interrupt
indicates that the new message is loaded into FIFO.
FIFO can be read by using FIFO Pointer bits, FP.
TABLE 23-5:
23.15.4
When an error occurs during transmission or reception
of a message, the message error flag, IRXIF, will be set
and if the IRXIE bit is set, an interrupt will be generated.
This is intended to be used to facilitate baud rate
determination when used in conjunction with Listen
Only mode.
