REGISTER 23-21: RXERRCNT: RECEIVE ERROR COUNT REGISTER
EXAMPLE 23-5:
© 2007 Microchip Technology Inc.
; Need to read a pending message from RXB0 buffer.
; To receive any message, filter, mask and RXM1:RXM0 bits in RXB0CON registers must be
; programmed correctly.
;
; Make sure that there is a message pending in RXB0.
BTFSS
BRA
; We have verified that a message is pending in RXB0 buffer.
; If this buffer can receive both Standard or Extended Identifier messages,
; identify type of message received.
BTFSS
BRA
; Read all 29-bits of Extended Identifier message.
...
; Now read all data bytes
MOVFF
...
; Once entire message is read, mark the RXB0 that it is read and no longer FULL.

READING A CAN MESSAGE
bit 7
REC7:REC0: Receive Error Counter bits
This register contains the receive error value as defined by the CAN specifications.
When RXERRCNT > 127, the module will go into an error-passive state. RXERRCNT does not
have the ability to put the module in “bus-off” state.
Legend:
R = Readable bit
-n = Value at POR

REC5
R-0
Preliminary
; Does RXB0 contain a message?
; No.
; Is this Extended Identifier?
; No.
; Yes.
; This will allow CAN Module to load new messages
; into this buffer.
Handle this situation...
This is Standard Identifier message.
This is Extended Identifier message.
