Question

The most important use of a timer inside the microcontroller is to generate a real-time clock. The clock ticks (the interrupt comes) at a rate determined by the crystal oscillator's frequency and the timer's count to overflow. Suppose the timer A is used to turn on/off a single LED every 600 ms. Please complete the following code (P2.0 is configured as an output to control the LED). void Ta0 (void) {TAOCTL = TASSEL_2 + TACLR; //SMCLK + clear TimerA0 TAOCCTLO = CCIE; //CCRO enable interrupt TAOCCRO =50000; //initial timer value TAOCTL| = MC_2; //continuous up} /* interrupt Routine*/ #pragma vector= TIMERO_AO_VECTOR _interrupt void timerA (void) {TAOCCRO+= 50000; //CCRO reload

Explanation / Answer

here the program is for that after turning on the led the controller waits for the delay period and then turns off the led and again waits for the delay period and then go back to the start

org 000h

loop:

clr p2.0

call delay

setb p2.0

call delay

jmp loop
