42.10.6.3.5 CAN interrupt pending 1 register
42.10.6.3.6 CAN interrupt pending 2 register
Table 1040.CAN new data 2 register (ND2, address 0x400E 2124) 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.
Table 1041.CAN interrupt pending 1 register (IR1, address 0x400E 2140) bit description
This register contains the INTPND bits of message objects 32 to 17. 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.

Rev. 00.13 — 20 July 2011
Description
New data bits of message objects 32 to 17.
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.
