; 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. And since we want banked method, we need to make sure
; that correct bank is selected.
BANKSEL TXB0CON
; Now load transmit data into TXB0 buffer.

; No need to load TXB0EIDL:TXB0EIDH, as we are transmitting Standard Identifier Message only.

; Need to transmit Standard Identifier message 123h using TXB0 buffer.

TRANSMITTING A CAN MESSAGE USING BANKED METHOD
TRANSMITTING A CAN MESSAGE USING WIN BITS
; 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. Continue to wait...
; WIN bits are in lower 4 bits only. Read CANCON
; register to preserve all other bits. If operation
; mode is already known, there is no need to preserve
; other bits.
; Clear WIN bits.
; Select Transmit Buffer 0
; Apply the changes.
; Load first data byte into buffer
; Access TXB0D0 via RXB0D0 address.
; Load SID2:SID0, EXIDE = 0
; Load SID10:SID3
; Normal priority; Request transmission
; Is it transmitted?
; No. Continue to wait...
