User manual
16.6.3.6 CAN interrupt pending 2 register
16.6.3.7 CAN message valid 1 register
16.6.3.8 CAN message valid 2 register
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.
Table 271. CAN interrupt pending 2 register (CANIR2, addresses 0x4005 0144) bit
This register contains the MSGVAL bits of message objects 16 to 1. By reading out the
MSGVAL bits, the CPU can check which Message Object is valid. The MSGVAL bit of a
specific Message Object can be set/reset by the CPU via the IFx Message Interface
Registers.
Table 272. CAN message valid 1 register (CANMSGV1, addresses 0x4005 0160) bit
This register contains the MSGVAL bits of message objects 32 to 17. By reading out the
MSGVAL bits, the CPU can check which Message Object is valid. The MSGVAL bit of a
specific Message Object can be set/reset by the CPU via the IFx Message Interface
Registers.
