Brne assembly instruction

WebBRNE (Branch If Not Equal) instruction is used for looping. BRNE instruction uses the zero or Z flag in the status register. CPU jumps to target address if zero flag is low. WebMay 15, 2024 · You can calculate the three loop count constants by working backwards from largest to smallest, then adding 0, 1, or 2 nop instructions to get the exact number of cycles. For example, recomputing for a 50 ms delay (800000 cycles) would work as follows: 800000/197122 = 4, remainder 11512. 11512/770 = 14, remainder 732. 732/3 = 244, …

WebThe problem is that the register r17, which you use as a PWM timing ramp, overflows twice every time you enter pwm_pre_loop:. when you increments it past 127, it overflows to −128; when you increment it past 255, it overflows to 0. When using a counter the way you are using r17 here, you usually have it overflow only once per cycle: either you consider it … WebDec 21, 2024 · 2 us if taken, 1 us if it fails.
