For/Break Instructions (FOR, FOR...DO, BRK, EXIT, RET) 477Example:The FOR instruction repeatedly executes routine_2 and incrementsvalue_2 by 1 each time. When value_2 is > 10 or a BRK instruction isenabled, the FOR instruction no longer executes routine_2.The RET instruction returns to the calling FOR instruction. The FORinstruction either executes the subroutine again and increments theIndex value by the Step size or, if the Index value exceeds theTerminal value, the FOR instruction is complete and execution moveson to the instruction that follows the FOR instruction.calling routinesubroutinePublication 1756-RM003I-EN-P - January 2007
