The following VHDL code has two inputs EN1 and EN2
one clock input and one output is z.
It has two T flip-flops are port mapped as shown in the below diagram.
Each flip-flop has one inout T
and clock input CLK and one output Q
First flip flop input is connected through a AND gate with inputs EN1 and EN2.
First flip-flop input is connected to the second flip-flop input and
Out put z is taken from OR gate with inputs t1_s and t2_s which are outputs of two flips.
The digram is shown in the below figure.

Manchester code is a coding scheme used to represent a bit in a data stream. A 'O' value of a bit is represented as a 0-to-1 transition in which the lead half is 'O' and the remaining half is '1'. Similarly, a '1' value of a bit is represented as a 1-to-transition, in which the lead half is 'l' and the remaining half is 0 For example, for the input string "110", the output is translated as: 110...
