ACEX 1K Programmable Logic Device Family Data Sheet
In addition to the six clear and preset modes, ACEX 1K devices provide a
chip-wide reset pin that can reset all registers in the device. Use of this
feature is set during design entry. In any of the clear and preset modes, the
chip-wide reset overrides all other signals. Registers with asynchronous
presets may be preset when the chip-wide reset is asserted. Inversion can
be used to implement the asynchronous preset. Figure 12 shows examples
of how to setup the preset and clear inputs for the desired functionality.
