You need to generate a 3906.25 Hz PWM waveform on RC2 using a 1:1 prescaled TMR1 ISR shown below. The duty cycle is set using a global uint8_t variable called dutyCycle.What is the value of scale?void myTMR1ISR(void) { if (PORTCbits.RC2 == 1) { LATCbits.LATC2 = 0; TMR1_WriteTimer(0x10000 - (MAX - scale*dutyCycle)); } else { LATCbits.LATC2 = 1; TMR1_WriteTimer(0x10000 - scale*dutyCycle); } PIR1bits.TMR1IF = 0;} Answer not given 4 Correct! 16 64 100
