3.8 CAN Interface

The SH7264 includes RCAN-TL1 (Renesas CAN Time Trigger Level 1), the controller area network. SH7264 RCAN-TL1
channels 0 and 1 are connected to the CAN connector (3-pin, 2.5 mm pitch) on the M3A-HS64G01 via the voltage level shifter
and the CAN driver IC.
The RCAN-TL1 channel 0 pin is also used as the SCIF channel 0 pin, and the IEBus
The figure below shows the CAN interface block diagram. Table 3.8.1 lists the jumpers setting (JP4 to JP6 on the M3A-HS64).
Table 3.8.2 and Table 3.8.3 list the jumpers setting (JP4, JP5, JP8, and JP9).
