Transmit
PIC18F2682/2685/4682/4685 devices of the pending
transmittable messages. This is independent from and
not related to any prioritization implicit in the message
arbitration scheme built into the CAN protocol. Prior to
sending the SOF, the priority of all buffers that are
queued for transmission is compared. The transmit

buffer with the highest priority will be sent first. If two
buffers have the same priority setting, the buffer with
the highest buffer number will be sent first. There are
four levels of transmit priority. If TXP bits for a particular
message buffer are set to ‘11’, that buffer has the high-
est possible priority. If TXP bits for a particular message
buffer are set to ‘00’, that buffer has the lowest possible
priority.
