User manual
8.14 Transmit Identifier Register (CAN1TID[1/2/3] - 0xE004 40[34/44/54],
8.15 Transmit Data Register A (CAN1TDA[1/2/3] - 0xE004 40[38/48/58],
CAN2TID[1/2/3] - 0xE004 80[34/44/54])
When the corresponding TBS bit in CANxSR is 1, software can write to one of these
registers to define the Identifier field of the next transmit message. Bits not listed read as 0
and should be written as 0. The register assumes two different formats depending on the
FF bit in CANTFI.
In Standard Frame Format messages, the CAN Identifier consists of 11 bits (ID.28 to
ID.18), and in Extended Frame Format messages, the CAN identifier consists of 29 bits
(ID.28 to ID.0). ID.28 is the most significant bit, and it is transmitted first on the bus during
the arbitration process. The Identifier acts as the message's name, used in a receiver for
acceptance filtering, and also determines the bus access priority during the arbitration
process.
Table 434. Transfer Identifier Register (CAN1TID[1/2/3] - address 0xE004 40[34/44/54],
Table 435. Transfer Identifier register when FF = 1
CAN2TDA[1/2/3] - 0xE004 80[38/48/58])
When the corresponding TBS bit in CANSR is 1, software can write to one of these
registers to define the first 1 - 4 data bytes of the next transmit message. The Data Length
Code defines the number of transferred data bytes. The first bit transmitted is the most
significant bit of TX Data Byte 1.
