we are using the ST3354DV.

Regarding to the Low Voltage Detect (LVD) circuitry:

An internal reset is generated by the LVD circuit when VCC drops below the reset threshold (2.4V-2.8V) while, the minimum required voltage for Vcc is 3V

a. What is the MCU/PLD state in such poor Vcc\Vdd supply (between 2.4V to 3V) ?

b. Is there any influence on PLD\CPU I/O status (between 2.4V to 3V - before the LVD reset the system) ?
