5.13.6.2.4 Receive/Transmit Priority
5.13.6.3 Configuring a Transmit Object
5.13.6.4 Updating a Transmit Object
Table 5-13 shows how a Transmit Object should be initialized.
3) Dir = ‘1’ (direction = transmit), RmtEn = ‘0’, UMask =’1’
The receive/transmit priority for the Message Objects is attached to the message number.
Message Object 1 has the highest priority, while Message Object 32 has the lowest priority. If
more than one transmission request is pending, they are serviced due to the priority of the
corresponding Message Object
Note: appl. = application software.
The Arbitration Register values ( ID28-0 and Xtd bit) are provided by the application. They define
the identifier and type of the outgoing message. If an 11-bit Identifier (“Standard Frame”) is used,
it is programmed to ID28 - ID18. The ID17 - ID0 can then be disregarded.
If the TxIE bit is set, the IntPnd bit will be set after a successful transmission of the Message
Object.
If the RmtEn bit is set, a matching received Remote Frame will cause the TxRqst bit to be set;
the Remote Frame will autonomously be answered by a Data Frame.
The Data Register values ( DLC3-0 , Data0-7 ) are provided by the application, TxRqst and RmtEn
may not be set before the data is valid.
The Mask Registers ( Msk28-0 , UMask , MXtd , and MDir bits) may be used ( UMask =’1’) to allow
groups of Remote Frames with similar identifiers to set the TxRqst bit. The Dir bit should not be
masked.
The software may update the data bytes of a Transmit Object any time through the IFn Interface
registers, neither MsgVal nor TxRqst have to be reset before the update.
Even if only a part of the data bytes are to be updated, all four bytes of the corresponding IFn
Data A Register or IFn Data B Register have to be valid before the contents of that register are
1
unchanged; the Remote Frame is ignored.
At the reception of a matching Remote Frame, the TxRqst bit of this Message Object is reset.
The arbitration and control field (Identifier + IDE + RTR + DLC) from the shift register is stored
in the Message Object of the Message RAM and the NewDat bit of this Message Object is
set. The data field of the Message Object remains unchanged; the Remote Frame is treated
similar to a received Data Frame.
