Fix your power supply issues. You can't expect the CPLD to work with an unreliable power supply.
New ContributorThanks, but I only have easier access to the boards. The power supply is new, and although there have been some defects, it should not be possible to modify it or add filters internally, due to the physical occupation of the internal area. The circuit that was microcontrolled in other versions was discretized, so it had greater internal occupation.
