In case of multipoint to multipoint applications the 6 MSBs of the SCI source address will
be defined by pinstrapping of the address pins A5 to A0. The two LSBs of the SCI source
address are constant ´10
a write command into the SCI configuration register. For applications with point to point
connections for the SCI interface the source address is not valid.
Because 14 bits are used for the register addresses in the SCI interface macro the two
MSBs of the 16 bit wide register addresses are set fixed to zero. (Because the MSBs for
global addresses are ´00
range, there is no problem.)
