PIC18F66K80 FAMILY
27.2.2
This section describes the dedicated CAN Transmit
Buffer registers and their associated control registers.
REGISTER 27-5:
DS39977C-page 404
Mode 0
Mode 1,2
Legend:
R = Readable bit
-n = Value at POR

Note 1:

This bit is automatically cleared when TXREQ is set.
While TXREQ is set, Transmit Buffer registers remain read-only. Clearing this bit in software while the bit is
set will request a message abort.
These bits define the order in which transmit buffers will be transferred. They do not alter the CAN
message identifier.
DEDICATED CAN TRANSMIT
BUFFER REGISTERS
bit 7
TXBIF: Transmit Buffer Interrupt Flag bit
1 = Transmit buffer has completed transmission of a message and may be reloaded
0 = Transmit buffer has not completed transmission of a message
TXABT: Transmission Aborted Status bit
1 = Message was aborted
0 = Message was not aborted
TXLARB: Transmission Lost Arbitration Status bit
1 = Message lost arbitration while being sent
0 = Message did not lose arbitration while being sent
TXERR: Transmission Error Detected Status bit
1 = A bus error occurred while the message was being sent
0 = A bus error did not occur while the message was being sent
TXREQ: Transmit Request Status bit
1 = Requests sending a message; clears the TXABT, TXLARB and TXERR bits
0 = Automatically cleared when the message is successfully sent
Unimplemented: Read as ‘ 0 ’
TXPRI<1:0>: Transmit Priority bits
11 = Priority Level 3 (highest priority)
10 = Priority Level 2
01 = Priority Level 1
00 = Priority Level 0 (lowest priority)
