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?
Datasheets, Manuals or Parts. They have an output whenever one of the inputs is active.
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!
HEF 4532 BT
You cannot service all 8 interrupting sources at the same time. Forums New posts Search forums.

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.
