PA[3] (IRQ0),
PA[6] (IRQ1) ,
PA[7] (IRQ2)
are enabled for both Rising and Falling Edge.
Program Outcome:
Rising Edge @ PA[3](IRQ0) => LED1 ON Falling Edge @ PA[3](IRQ0) => LED1 OFF Rising Edge @ PA[6](IRQ1) => LED2 ON Falling Edge @ PA[6](IRQ1) => LED2 OFF Rising Edge @ PA[7](IRQ2) => LED3 ON Falling Edge @ PA[7](IRQ2) => LED3 OFF
Connections:
Connect External Interrupt at PA[3],PA[6] & PA[7] PA[3] => PCR[3] => PIN 90 => IRQ0 PA[6] => PCR[6] => PIN 119 => IRQ1 PA[7] => PCR[7] => PIN 104 => IRQ2
LED No. => Port No. => Pad No. => Pin No.(144-pin LQFP package) LED1 => PE[4] => PCR[68] => PIN 132 LED2 => PE[5] => PCR[69] => PIN 133 LED3 => PE[6] => PCR[70] => PIN 139 LED4 => PE[7] => PCR[71] => PIN 140 SWITCH No. => Port No. => Pad No. => Pin No.(144-pin LQFP package) SWITCH1 => PE[0] => PCR[64] => PIN 10 SWITCH2 => PE[1] => PCR[65] => PIN 12 SWITCH3 => PE[2] => PCR[66] => PIN 128 SWITCH4 => PE[3] => PCR[67] => PIN 129
NOTE:
IRQ_SET0: IRQ 0 to 7 => VectorNum = 41 :(IRQ 0 to 7 have same Priority) IRQ_SET1: IRQ 8 to 15 => VectorNum = 42 :(IRQ 8 to 15 have same Priority) IRQ_SET2: IRQ 16 to 23 => VectorNum = 43 :(IRQ 16 to 23 have same Priority) > When 1 interrupt is executing, another interrupt doesn't get triggered. > Program developed by Akshay P Daga
