Two additional serial interfaces are included to enable device programming and
controlling:
By using the SCI Interface, the OctalFALC
interworking devices like the SDC16. The SCI is used as interface also in the Infineon
SHDSL- and ADSL-PHYs so that implementation of different line transmission
technologies on the same line card easily is possible. The SCI interface is a three-wire
bus and optionally replaces the parallel processor interface to reduce wiring overhead
on the PCB, especially if multiple devices are used on a single board. Data on the bus is
HDLC encapsulated and uses a message-based communication protocol. The
OctalFALC
If SCI interface with multipoint to multipoint configuration is used, address pins A(5:0) are
used for SCI source (slave) address pin strapping.
In compatibility mode (pin COMP = 1) these both new interfaces are also supported.
The four possible interface modes - two microconroller modes and two serial interface
modes - are selected by using the interface mode selection pins IM(1:0). This selection
is valid immediately after reset becomes inactive.
After changing of the interface mode by IM(1:0), a hardware reset must be applied.
Note that after a reset writing into or reading from OctalFALC
or SPI-Interface is not possible until the PLL is locked: If the SCI-Interface is used no
acknowledge message will be send by the OctalFALC
