Me: OK.

John: If the direction of current flow of port B is "occassionally" same as that of port A, there will be carrier wave formed.

.

Me: OK.

John: Look at the picture above. Those carrier wave will affect the data input of Port A.

Me: Those carrier wave also affect the Clock line. Consequently, register R1, 2, 3 become unstable.
