User manual
16.6.3.1 CAN transmission request 1 register
16.6.3.2 CAN transmission request 2 register
16.6.3.3 CAN new data 1 register
This register contains the TXRQST bits of message objects 1 to 16. By reading out the
TXRQST bits, the CPU can check for which Message Object a Transmission Request is
pending. The TXRQST bit of a specific Message Object can be set/reset by the CPU via
the IFx Message Interface Registers or by the Message Handler after reception of a
Remote Frame or after a successful transmission.
Table 266. CAN transmission request 1 register (CANTXREQ1, address 0x4005 0100) bit
This register contains the TXRQST bits of message objects 32 to 17. By reading out the
TXRQST bits, the CPU can check for which Message Object a Transmission Request is
pending. The TXRQST bit of a specific Message Object can be set/reset by the CPU via
the IFx Message Interface Registers or by the Message Handler after reception of a
Remote Frame or after a successful transmission.
Table 267. CAN transmission request 2 register (CANTXREQ2, address 0x4005 0104) bit
This register contains the NEWDAT bits of message objects 16 to 1. By reading out the
NEWDAT bits, the CPU can check for which Message Object the data portion was
updated. The NEWDAT bit of a specific Message Object can be set/reset by the CPU via
the IFx Message Interface Registers or by the Message Handler after reception of a Data
Frame or after a successful transmission.
