(1) PREQ3 can be programmed for two different input supplies (1.2 V/1.8 V) and, as such, has a configurable input threshold.
(2) Applying 1.8-V input logic on the PREQ3 ball when the 1.2-V supply mode is selected does not damage the PREQ3 input buffer. Nevertheless, because the threshold is reduced to its 1.2-V configuration, the input buffer is more sensitive to the low 1.8-V logic level.
