Consider the circuit shown above. If the input R is at logic level “0” (R = 0) and input S is at logic level “1” (S = 1), the NAND gate Y has at least one of its inputs at logic “0” therefore, its output Q must be at a logic level “1” (NAND Gate principles). Output Q is also fed back to input “A” and so both inputs to NAND gate X are at logic level “1 ...

WebThe common clk framework is an interface to control the clock nodes available on various devices today. This may come in the form of clock gating, rate adjustment, muxing or other operations. This framework is enabled with the CONFIG_COMMON_CLK option. The interface itself is divided into two halves, each shielded from the details of its ...
