8.13.6.2 Node Interface Pseudo Code. 
If a node supports boot software then the operational software only
needs minimum support of this service. This is true for nodes with boot software because a service $34
transitions the program operation back to the boot software (see service $34) and the $34 service is required
before the $36 service is allowed. ECUs with boot software only need to support the Serv_36_Msg_Recvd()
pseudo code in the operational software and the Boot_36_Msg_Recvd() in the boot software. ECUs that do not
have boot software shall support the functionality of the Boot_36_Msg_Recvd() pseudo code in the operational
software.
BEGINFUNCTION Serv_36_Msg_Recvd()
send Negative Response ($7F $36 $22)/* conditions not correct since the $34 service is not active if the ECU
is executing the operational software. */
ENDFUNCTION
BEGINFUNCTION Boot_36_Msg_Recvd()
/* The check below for $Level $80 is only needed if that sub function is supported by the ECU */
IF ( (($Level != $00) AND ($Level != $80)) OR
(message_data_length < (2+C_NumAddrBytes)) OR
(($Level = $00) AND (message_data_length < (3+C_NumAddrBytes ))) ) THEN
send Negative Response ($7F $36 $12) /* invalid format */
ELSE IF (TransferData_Allowed = NO) THEN
send Negative Response ($7F $36 $22)

C_NumAddrBytes) is invalid)) THEN

C
) THEN

perform any necessary actions to the data block /*, i.e., program to flash memory etc.*/
ENDIF
IF (errors are detected) THEN
send the appropriate negative response ($7F $36 $22) or ($7F $36 $83) or ($7F $36 $85).
