Transmission Request Register 1 (CAN_TXREQ1)
These registers hold the TxRqst bits of the 32 Message Objects. By reading the TxRqst bits, the
software can check which Message Object in a Transmission Request is pending. The TxRqst bit of a
specific Message Object can be set/reset by the application software through the IFn Message
Interface Registers or by the Message Handler after reception of a Remote Frame or after a
successful transmission.
