Deviations 2 Functional Deviations CAN 2 Unexpected Remote Frame Transmission The on chip CAN module may send an unexpected remote frame with the identifier 0 when a pending transmit request of a message object is disabled by software There are three possibilities to disable a pending transmit request of a message object n 1 14 e Set CPUUPDn element e Reset TXRQn element e Reset MSGVALn element Either of these actions will prevent further transmissions of message object n The symptom described above occurs when the CPU accesses CPUUPD TXRQ or MSGVAL while the pending transmit request of the corresponding message object is transferred to the CAN state machine just before start of frame transmission At this particular time the transmit request is transferred to the CAN state machine before the CPU prevents transmission In this case the transmit request is still accepted from the CAN state machine However the transfer of the identifier the data length code and the data of the corresponding message object is prevented Then the pre charge values of the internal hidden buffer are transmitted instead this causes to a remote frame transmission with identifier 0 11 bit and data length code 0 This behavior occurs only when the transmit request of message object n is pending and the transmit requests of other message objects are not active single transmit request If this remote frame loses arbitration to a data fra
