In simulation mode, operation is user-programmable with up to 99 program steps that can reference up to 50 "parameter buffers" (registers). Some standard tests like all-character tests or "quick brown fox" tests are predefined. | In simulation mode, operation is user-programmable with up to 99 program steps that can reference up to 50 "parameter buffers" (registers).
