EXAMPLE 27-4:
2011 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. Use WIN bits to map it to RXB0 area.
MOVF
ANDLW
IORLW
MOVWF
; Now TXB0 is mapped in place of RXB0. All future access to RXB0 registers will actually
; yield TXB0 register values.
; Load transmit data into TXB0 buffer.
MOVLW
MOVWF
; Load rest of the data bytes - up to 8 bytes into “TXB0” buffer using RXB0 registers.
...
; Load message identifier
MOVLW
MOVWF
MOVLW
MOVWF
; No need to load RXB0EIDL:RXB0EIDH, 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.
; If required, reset the WIN bits to default state.

TRANSMITTING A CAN MESSAGE USING WIN BITS
Preliminary
; 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...
