Uaually this series of chips like DSxxx or M48xxx are Real Time Clock plus RAM,with lithium energy source. After AutoPrgoram is ok,read or verify again may cause the RAM data change.Cancel the Insertion Test is just avoided this situation. So when Prgoram ok,do not chick others.use it on board.Check the board work or not. But it must be sure the source files are right.Read from chip can not be reliable. |
