A semiconductor device is disclosed which comprises a clock generating circuit generating first and second divided clocks by dividing an input clock by first and second division number, respectively, and a counter circuit including a shift register having a plurality of stages that sequentially shifts an input signal and outputs an output signal delayed based on setting information. The system includes a configuration determination resource configured for determining the router configurations from the multiple routers, and a device analyzer resource configured for determining for each router configuration a corresponding candidate configuration to be utilized in the single router configuration. Further provided are pharmaceutical compositions, comprising the kinase inhibitors or the prodrugs, and the use of such compositions in therapy, in particular for treating cancer. Also, the receiver is arranged to change from the dormant mode to the active mode in response to a instruction received from external to the receiver and made whilst the receiver is operating in the dormant mode.
