You have programmed the DE 1-SoC interval timer to count down and repeat. What is the best way to check if a countdown has completed? Reset Selection Assume the timer base address is stored in ro When the countdown is complete, we want to branch to countdown_complete Question 6 of 6 1.0 Points A timer_loop: ldr ri, [ro, #8] Idr r2, [ro, #12] add r1, r2, lsl #16 cmp r1, #0 beq countdown_complete b timer_loop Consider a dual-slope inverting integrator ADC. This integrates the signal vs for known number of clock cycles K, then integrates - Vref for an unknown number of clock cycles L. What can we say about the relationship between K and L? Assume v is a nice, well-behaved signal that can be successfully and accurately converted to a binary sequence using this ADC (.e., Vs is not +, or negative, or oscillating at extremely high frequencies, or any other weird hypotheticals). OB. timer_loop: str ro, [re, #16] Idr r1, [re, #16] ldr r2, [ro, #20] add ri, r2, Isl #16 cmp r1, #0 beq countdown_complete b timer_loop O A. We must have k>L. OB. We must have KL. OB. We must have K
