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