This is a CMOS JK Flip-Flop that is essentially a modified version of an SR-Latch. It is built from cross-coupled CMOS NAND gate circuits.
⚠️ The Toggle action where inputs, C, J, K are all High is presently not working properly. Some redesign is needed.
📚 Action taken by Flip-Flop is to either Set, Reset, Toggle, or Hold it's present value depending on the K, J, and Clock (C) inputs.
