The SH7264 includes an IEBus
TM
controller (IEB). IEBus
TM
(Inter Equipment Bus

) is the bus for digital data transfer system
on a small scale. The SH7264 IEB pin is connected to the IEBus connector (4-pin, 2.5 mm) via the voltage level shifter and the
IEBus
TM
driver IC on the M3A-HS64G02.
The IEB pin is also used as the SCIF channel 0 pin and the RCAN-TL1 channel 0 pin.
