High Speed Serial Interfaces
Four, full modem, serial ports (SER1, 2, 3 and 4) are available on the EBC2 SAI. Depending
on the E²Brain™ module employed with the EBC2 up to eight signals per port are provided to
realize asynchronous or synchronous (EB425) high speed serial links interfaced using dedicat-
ed controlling/handshaking.
The following table provides a summary of the HSS signals implemented on the Communica-
tions Interface connector.
