USER’S MANUAL
3-V / 5-V Sel
PRDS
This pad has logic for a 3-V input/output function as well as a 5-V input/output function.
A “3-V / 5-V sel” interface signal determines which driver gets selected.
In this pad type the data interface to the internal logic has separate paths for input and
output. The 3-V receiver has 2 possible paths: with or without hysteresis. The hyst_sel
signal selects the appropriate path.
