16.6.3.4 CAN new data 2 register
16.6.3.5 CAN interrupt pending 1 register
Table 268. CAN new data 1 register (CANND1, address 0x4005 0120) 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.
Table 269. CAN new data 2 register (CANND2, address 0x4005 0124) bit description
This register contains the INTPND bits of message objects 16 to 1. By reading out the
INTPND bits, the CPU can check for which Message Object an interrupt is pending. The
INTPND 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 or after a
successful transmission of a frame. This will also affect the value of INTPND in the
Interrupt Register.

Description
0 = This message object is ignored by the message
handler.
1 = This message object is the source of an interrupt.
Reserved
Description
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
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.
