LFAST pad electrical characteristics

The LFAST(LVDS Fast Asynchronous Serial Transmission) pad electrical characteristics

apply to both the SIPI and high-speed debug serial interfaces on the device. The same

LVDS pad is used for the Microsecond Channel (MSC) and DSPI LVDS interfaces, with

different characteristics given in the following tables.
