    Description:

    Conditional relative branch. Tests the Overflow flag (V) and branches relatively to PC if V is cleared. This instruction branches relatively to PC in either direction (PC - 63 ≤ destination ≤ PC + 64). The parameter k is the offset from PC and is represented in two's complement form. (Equivalent to instruction BRBC 3,k).

    Operation:

    If V = 0 then PC ← PC + k + 1, else PC ← PC + 1

    Syntax: Operands: Program Counter:

    BRVC k -64 ≤ k ≤ +63 PC ← PC + k + 1

    PC ← PC + 1, if condition is false
