Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. These are also priority encoder circuits. Hi, As you will want to know which is the interrupting source, you could use a HEF 8 input priority encoder.

Replacement Transformer Started by ncag Today at 7: Input source 0 has lowest priority and source 7 has the highest. Papabravo Well-Known Member Feb 28, You must log in or register to reply here. How to convert external Interrrupt to Multiple Interrupts.


Depending on the value on these three pins 0 to 7 you will know which interrupt line, on the “priority 44532 circuit”, you have to service. To participate hrf need to register. Have you read the datasheets on priority encoder devices?

Pioneer Elite vsxtx water damage no power Started by Watin 15 minutes ago Replies: On the it is called EO and it is pin 15 You can also look for a 74xx or a 74xx This is what the priority encoder does, it encodes a 3 bit pattern, which unique for each external source. What does the 3 bit address related to the calling source do I am totally confused.

If ‘one of the eight’ ext sources, requesting an intr, generated a 3 bit code which is unique for that source, then heg PIC prog would know which Interrupt subr in your prog to execute. Welcome to our site!

Hi Eric, I will answer your question: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at No And continue your, well explained, story A PIC prog reads these 3 input port bits, so it knows which ext intr to service. For a better experience, please enable JavaScript in your browser before proceeding. I believe that it even has the same pinout as the Articles Top Articles Search resources.

Also there is a common intr output pin, to drive the MCU’s intr pin. Click here to register now. So a decision has to made which ext source has intr priority. Can anyone show me schemmatic for this.
