Exercise III: Processing interrupts caused by changes on pins PB4-PB7: Program "intportb.asm" illustrates how interrupt can be employed for indicating changes on pins RE RB7. Upon pushing any of the buttons, program enters the interrupt routine and determines which caused an interrupt. The figure bellow represents the wiring system of the PIC, the push buttons and the LEDs. RAZ DRA Q RAI RAD ODCI 09C2 PIC 16F84 wh PONT P2 R06 RBS 104
