PIC18F66K80 FAMILY
27.6.3
Transmit
PIC18F66K80 family devices of the pending transmitta-
ble 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 Start-of-Frame (SOF), the priority of all buf-
fers 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 the TXP bits for a
particular message buffer are set to ‘ 11 ’, that buffer has
the highest possible priority. If the TXP bits for a partic-
ular message buffer are set to ‘ 00 ’, that buffer has the
lowest possible priority.
