Computer Science Using three D flip-flops and a PLA implement a 3-bit Gray code up/down counter. The single bit input X = 0 denotes that the counter counts up at each clock cycle whereas X = 1 denotes that the counter counts down at each clock cycle. The outputs are the value of the counter. A Gray code is a sequence of binary numbers with the property that no more than 1 bit changes in going from one element of the sequence to another. For example, a 3-bit binary Gray code up sequence is given by: 000, 001, 011, 010, 110, 111, 101, 100. The Gray code is cyclic so that the value after 100 in the sequence is 000. The Gray code down sequence is the above sequence traversed in the opposite direction.

Connect a 5*7 dot-matrix display to the 8051-microcontroller (Draw the schematic on paper). Then, display the content of variable NUMBER on the display, digit by digit every one second. for example if NUMBER=249, then "2" will be displayed for one second, after that digit "4" and finally digit "9" will be displayed for a whole second. Assume that the necessary lookup table exists in Memory at address OXF000.
