edge triggering: Positive-edge triggering – the flip-flop output can only change on the positive edges of the clock
Negative-edge triggering – the flip-flop output can only change on the negative edges of the clock Master ff:
The master is enabled when C = 1 so responds to any input changes during the positive clock cycle. The output Q of the master is transferred to the slave on the negative clock edge (when C = 0).
The master flip-flop reads the input values on the positive edge of the clock, and the output Q of the master is transferred to the slave on the negative clock edge.

edge triggered flip flops may cause race around condn whereas master slave flip flops eliminate it...
