JK-FF

Edge-triggered JK flip-flop. J=1 sets, K=1 resets, J=K=1 toggles, J=K=0 holds. Optional synchronous active-high reset.

Parameters

Name	Label	Type	Default	Units	Description
q0	q₀	int	0	—	Initial value of the stored state q at sim_time = 0.
has_rst	Reset port	enum (disabled / enabled)	0	—	When enabled, exposes a synchronous active-high reset port. On a clock rising edge, if rst != 0 then q := 0 (per-bit clear).
