RL78/D1A CHAPTER 14 CAN CONTROLLER 14.14 Time Stamp Function CAN is an asynchronous, serial protocol. All nodes connected to the CAN bus have a local, autonomous clock. As a consequence, the clocks of the nodes have no relation (i.e., the clocks are asynchronous and may have different frequencies). In some applications, however, a common time base over the network (= global time base) is needed. In order to build up a global time base, a time stamp function is used. The essential mechanism of a time stamp function is the capture of timer values triggered by signals on the CAN bus. 14.14.1 Time stamp function The CAN controller supports the capturing of timer values triggered by a specific frame. An on-chip 16-bit capture timer unit in a microcontroller system is used in addition to the CAN controller. The 16-bit capture timer unit captures the timer value according to a trigger signal (TSOUT) for capturing that is output when a data frame is received from the CAN controller. The CPU can retrieve the time of occurrence of the capture event, i.e., the time stamp of the message received from the CAN bus, by reading the captured value. TSOUT signal can be selected from the following two event sources and is specified by the TSSEL bit of the C0TS register. - SOF event (start of frame) (TSSEL = 0) - EOF event (last bit of end of frame) (TSSEL = 1) The TSOUT signal is enabled by setting the TSEN bit of the C0TS register to 1. TSOUT Figure 14-61. Timing Diagram of Capture Signal TSOUT SOF SOF SOF SOF TSOUT signal toggles its level upon occurrence of the selected event during data frame reception (in the above timing diagram, the SOF is used as the trigger event source). To capture a timer value by using TSOUT signal, the capture timer unit must detect the capture signal at both the rising edge and falling edge. This time stamp function is controlled by the TSLOCK bit of the C0TS register. When TSLOCK is cleared to 0, TSOUT bit toggles upon occurrence of the selected event. If TSLOCK bit is set to 1, TSOUT toggles upon occurrence of the selected event, but the toggle is stopped as the TSEN bit is automatically cleared to 0 as soon as the message storing to the message buffer 0 starts. This suppresses the subsequent toggle occurrence by TSOUT, so that the time stamp value toggled last (= captured last) can be saved as the time stamp value of the time at which the data frame was received in message buffer 0.

Under development Preliminary document Specifications in this document are tentative and subject to change. RL78/D1A CHAPTER 14 CAN CONTROLLER Caution The time stamp function using TSLOCK bit is to stop toggle of TSOUT bit by receiving a data frame in message buffer 0. Therefore, message buffer 0 must be set as a receive message buffer. Since a receive message buffer cannot receive a remote frame, toggle of TSOUT bit cannot be stopped by reception of a remote frame. Toggle of TSOUT bit does not stop when a data frame is received in a message buffer other than message buffer 0. For these reasons, a data frame cannot be received in message buffer 0 when the CAN module is in the normal operation mode with ABT, because message buffer 0 must be set as a transmit message buffer. In this operation mode, therefore, the function to stop toggle of TSOUT bit by TSLOCK bit cannot be used. By switching the input source (by using TMCAN0), the capture trigger signal (TSOUT of CAN Controller channel 0) can be input to channel 4 of timer array unit 1 without connecting TSOUT of CAN controller channel 0 and TI14 externally. By switching the input source (by using TMCAN1), the capture trigger signal (TSOUT of CAN Controller channel 1) can be input to channel 5 of timer array unit 1 without connecting TSOUT of CAN Controller channel 1 and TI15 externally.
