What is the meaning of "I/O Tristate Voltage Applied" and "Dedicated Input Voltage Applied" specified in the Absolute Maximum Ratings section of MachXO data sheet?
Solution: There are two cases where an IO pad is driven by an external source. One is the case of a dedicated input pad, and the other is a bi-directional IO pad in which its output can be tri-stated. The "Dedicated Input Voltage Applied" and "I/O ...
