WebMay 15, 2024 · The dec instructions decrement the registers and then the brne instructions compare the result with zero - each loop will run until the associated register is zero, at which point execution will 'fall through' to the next instruction. If the register is zero on entering the loop, dec will cause it to wrap around to 255. WebIf the brne instruction found a 1 in the zero flag bit it would not branch and instead it would just continue to the next line which would clr overflows resetting it to 0.
