Can EPM3032 GLCK2/ GCLRn/ OE1/ GCLK1 be used as INPUT pins like regular I/O pins? - Can EPM3032 GLCK2/ GCLRn/ OE1/ GCLK1 be used as INPUT pins like regular I/O pins? @EPM3032ATC44-10N @CPLD @Quartus EPM3032ATC44-10N CPLD product Pin 37: GLCK1 Pin 38: OE1 Pin 39: GCLRn Pin 40: GCLK2 Can the pin be used like a regular I/O port? Can it only be used on the INPUT pin? Pins 37 to 40 above are required. but Since it seems to be designated as a pin that plays several important roles, such as the global OE1 pin, I would like to inquire whether it can be used as a basic I/O port or INPUT pin.

For more information, you can refer to the device block diagram as illustrated in the page 5 from below link: https://www.intel.com/content/www/us/en/content-details/654926/data-sheet-max-3000a-programmable-logic-device-family.html?wapkw=max%203000a Replies: Re: Can EPM3032 GLCK2/ GCLRn/ OE1/ GCLK1 be used as INPUT pins like regular I/O pins? Yes, those pins all drive into the internal PIA matrix and thus can be used as an input into any logic equation. Inputs only however, there is no output capability on those pins.
