42.10.6.3.2 CAN transmission request 2 register
42.10.6.3.3 CAN new data 1 register
42.10.6.3.4 CAN new data 2 register
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 1038.CAN transmission request 2 register (TXREQ2, address 0x400E 2104) 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.
Table 1039.CAN new data 1 register (ND1, address 0x400E 2120) bit description
This register contains the NEWDAT bits of message objects 32 to 17. 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.

Description
New data bits of message objects 16 to 1.
0 = No new data has been written into the data portion
of this Message Object by the Message Handler since
last time this flag was cleared by the CPU.
1 = The Message Handler or the CPU has written new
data into the data portion of this Message Object.
Reserved
Description
Transmission request bit of message objects 32 to 17.
0 = This message object is not waiting for
transmission.
1 = The transmission of this message object is
requested and not yet done.
