I checked the contents of Accumulator after each reading of Port0 and displayed it on LCD which was not what was expected.So the problem must be with the power up sequence as it was not reading 1EH.When I skipped the first three CJNE instruction the programm went alright.
PS: Even Google had no information related to power up sequence. |
