(4) When you pushing PF11 again, the pattern will go back to the case (1), and so on… Some Hints All button interrupts are through IVG12, so actually, pushing any button, the same interrupt will generate. To differentiate which button is pushed, you can read the value of *pFIO_FLAG_C. If button PFn is pushed, the corresponded bit (nth bit) of *pFIO_FLAG_C is 1, the other bits are 0. For details see chapter 14 PROGRAMMABLE FLAGS in “ADSP-BF533 Blackfin Processor Hardware Reference” manual. In each ISR, one need to confirm interrupt handling (Clear the interrupt) You should modify the ISR for timer0 this time. The register * pFlashA_PortB_Data will control which LED will be lit on.
