RL78/D1A CHAPTER 14 CAN CONTROLLER 14.10.2 Transmit history list function The transmit history list (THL) function records in the transmit history list the number of the transmit message buffer from which data or remote frames have been were sent. The THL consists of storage elements equivalent to up to seven messages, the last out-message pointer (LOPT) with the corresponding C0LOPT register, and the transmit history list get pointer (TGPT) with the corresponding C0TGPT register. The THL is undefined immediately after the transition of the CAN module from the initialization mode to one of the operation modes. The C0LOPT register holds the contents of the THL element indicated by the value of the LOPT pointer minus 1. By reading the C0LOPT register, therefore, the number of the message buffer that transmitted a data frame or remote frame first can be checked. The LOPT pointer is utilized as a write pointer that indicates to what part of the THL a message buffer number is recorded. Any time a data frame or remote frame is transmitted, the corresponding message buffer number is recorded to the THL element indicated by the LOPT pointer. Each time recording to the THL has been completed, the LOPT pointer is automatically incremented. In this way, the number of the message buffer that has received and stored a frame will be recorded chronologically. The TGPT pointer is utilized as a read pointer that reads a recorded message buffer number from the THL. This pointer indicates the first THL element that the CPU has not yet read. By reading the C0TGPT register by software, the number of a message buffer that has completed transmission can be read. Each time a message buffer number is read from the C0TGPT register, the TGPT pointer is automatically incremented. If the value of the TGPT pointer matches the value of the LOPT pointer, the THPM bit (transmit history list pointer match) of the C0TGPT register is set to 1. This indicates that no message buffer numbers that have not been read remain in the THL. If a new message buffer number is recorded, the LOPT pointer is incremented and because its value no longer matches the value of the TGPT pointer, the THPM bit is cleared. In other words, the numbers of the unread message buffers exist in the THL. If the LOPT pointer is incremented and matches the value of the TGPT pointer minus 1, the TOVF bit (transmit history list overflow) of the C0TGPT register is set to 1. This indicates that the THL is full of message buffer numbers that have not been read. If a new message is received and stored, the message buffer number recorded last is overwritten by the number of the message buffer that transmitted its message afterwards. After the TOVF bit has been set (1), therefore, the recorded message buffer numbers in the THL do not completely reflect the chronological order. However the other transmitted messages can be found by a CPU search applied to all transmit message buffers unless the CPU has not overwritten a transmit object in one of these buffers beforehand. In total up to six transmission completions can occur without overflowing the THL. Caution If the history list is in the overflow condition (TOVF is set), reading the history list contents is still possible, until the history list is empty (indicated by THPM flag set). Nevertheless, the history list remains in the overflow condition, until TOVF is cleared by software. If TOVF is not cleared, the THPM flag will also not be updated (cleared) upon successful transmission of a new message. This may lead to the situation, that THPM indicates an empty history list, although a successful transmission has taken place, while the history list is in the overflow state (TOVF and THPM are set).
