An absolute address is represented by the contents of a register. This addressing mode is absolute in the sense that it is not specified relative to the current instruction address.
Both the Branch Conditional to Link Register instructions and the Branch Conditional to Count Register instructions use an absolute addressing mode. The target address is a specific register, not an input operand. The target register is the Link Register (LR) for the Branch Conditional to Link Register instructions. The target register is the Count Register (CR) for the Branch Conditional to Count Register instructions. These registers must be loaded prior to execution of the branch conditional to register instruction.
