Signals in 8085
Web8085 MP has two pins HOLD and HLDA which are used for DMA operation. First, DMA controller sends a request by making Bus Request (BR) control line high. When MP receives high signal to HOLD pin, it first completes the execution of current machine cycle, it takes few clocks and sends HLDA signal to the DMA controller. Websample injection to check the signal in blank sample in the form of chromatogram. 2.5.4 Precision and accuracy Precision was described as closeness of agreement between the repeated individual that measures of the analyte. It is expressed in the form of coefficient of variation (CV). Accuracy was defined as the closeness of the
