Conditional relative branch. Tests the Negative Flag (N) and branches relatively to PC if N is cleared. This instruction branches relatively to PC in either direction (PC - 63 ≤ destination ≤ PC + 64). Parameter k is the offset from PC and is represented in two’s complement form. (Equivalent to instruction BRBC 2,k.)
