4.8 CAN Interface
The SH7264 includes an RCAN-TL1 (Renesas CAN Time Trigger Level 1), the Controller Area Network. RCAN-TL1 channels
0 and 1 are connected to the CAN connector (3-pin, 2.5 mm pitch) on the M3A-HS64G02 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
TM
controller (IEB) pin.
The figure below shows the CAN interface block diagram. Table 4.8.1 lists the jumpers setting (JP4 to JP6 on the M3A-HS64).
Table 4.8.2 and Table 4.8.3 list jumpers setting (JP4, JP5, JP8, and JP9).
