WebJun 17, 2016 · The AVR BRNE instruction is a 16 bit op-code, 7 bits of which are the branch offset. This 7 bit signed operand can have a value k in the range -64 ≤ k ≤ +63.The PC is modified by k +1 (i.e. -63 to +64). If the jump is further then that, a relative branch is unsuitable. You either need to locate the target closer to the branch, or use an … WebWelcome to tutorial number 3! Before we get started I want to make a philosophical point.
