Reference Manual
The HSMC interface has programmable bi-directional I/O pins that can be used as
2.5-V LVCMOS, which is 3.3-V LVTTL-compatible. These pins can also be used as
various differential I/O standards including, but not limited to, LVDS, mini-LVDS,
and RSDS with up to 17 full-duplex channels.
1
As noted in the
manual, LVDS and
single-ended I/O standards are only guaranteed to function when mixed according to
either the generic single-ended pin-out or generic differential pin-out.
Table 2–21
lists the HSMC interface pin assignments, signal names, and functions.
