EXAMPLE 23-3:
 2004 Microchip Technology Inc.
; Need to transmit Standard Identifier message 123h using TXB0 buffer.
; To successfully transmit, CAN module must be either in Normal or Loopback mode.
; TXB0 buffer is not in access bank.
; that correct bank is selected.
BANKSEL TXB0CON
; Now load transmit data into TXB0 buffer.
MOVLW
MOVWF
; Load rest of data bytes - up to 8 bytes into TXB0 buffer.
...
; Load message identifier
MOVLW
MOVWF
MOVLW
MOVWF
; No need to load TXB0EIDL:TXB0EIDH, as we are transmitting Standard Identifier Message only.
; Now that all data bytes are loaded, mark it for transmission.
MOVLW
MOVWF
; If required, wait for message to get transmitted
BTFSC
BRA
; Message is transmitted.

TRANSMITTING A CAN MESSAGE USING BANKED METHOD
PIC18F6585/8585/6680/8680
; One BANKSEL in beginning will make sure that we are
; in correct bank for rest of the buffer access.
; Load first data byte into buffer
; Compiler will automatically set “BANKED” bit
; Load SID2:SID0, EXIDE = 0
; Load SID10:SID3
; Normal priority; Request transmission
; Is it transmitted?
; No.
And since we want banked method, we need to make sure
Continue to wait...
