Section 19 Controller Area Network (RCAN-ET)
Important: Although core of RCAN-ET is designed based on a 32-bit bus system, the whole
RCAN-ET including MPI for the CPU has 16-bit bus interface to CPU. LongWord (32-bit)
accesses are converted into two consecutive word accesses by the bus interface.
19.2.2
(1)
The MPI allows communication between the Renesas CPU and RCAN-ET's registers/mailboxes to
control the memory interface. It also contains the Wakeup Control logic that detects the CAN bus
activities and notifies the MPI and the other parts of RCAN-ET so that the RCAN-ET can
automatically exit the Sleep mode.
It contains registers such as MCR, IRR, GSR and IMR.
(2)
The Mailboxes consists of RAM configured as message buffers and registers. There are 16
Mailboxes, and each mailbox has the following information.
<RAM>
• CAN message control (identifier, rtr, ide,etc)
• CAN message data (for CAN Data frames)
• Local Acceptance Filter Mask for reception
<Registers>
• CAN message control (dlc)
• 3-bit wide Mailbox Configuration, Disable Automatic Re-Transmission bit, Auto-
