if what Mr. Erik Malaund said is true, (that the Xdata keeps the higher byte '0' on P2
it is; however the high MAY be nonzero depending thus enabling my rtcce, why aren't my leds aren't being on? whose latch enable is on P2.0. more over after getting low, how come it become high immediately without giving it in the program? Please explain me. some devices (read datasheets) mneed chip enable set xxx time before the read/write and therefore using xbyte may have very variying effects Erik |
