    Description:

    Conditional relative branch. Tests the Carry flag (C) and branches relatively to PC if C is set. 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 the section called “ BRBS - Branch if Bit in SREG is Set” 0,k).

    Operation:

    If C = 1 then PC <- PC + k + 1, else PC <- PC + 1

    Syntax: Operands: Program Counter:

    BRCS k -64 ≤ k ≤ +63 PC <- PC + k + 1

    PC <- PC + 1, if condition is false
