Testing the interrupt sources of a microprocessor

摘要: A method of testing the interrupt sources a microprocessor having number interrupts which are each operable to execute an service routine when enabled, default priority level and associated memory, order in they be serviced, comprising steps of: a) sorting descending order; b) determining array levels assigned pre-arranged sequence selections order, consisting lowest level; from highest c) incrementing global counter; d) assigning selected group interrupts, remainder assuming their pre-assigned e) enabling all simultaneously so that executes its routine; f) transferring value counter into memory executed g) repeating until is completed; h) comparing values after completion with expected comparison whether there error interrupts.
