Class Members
u32	gap_tolerance_ns = 0	Maximum gap duration to tolerate (0 = no gap tolerance, treat as error) Pulses longer than reset_min_us but shorter than gap_tolerance_ns are skipped during decoding without triggering errors. Useful for PARLIO ~20us DMA gaps between frames.
u32	reset_min_us	Reset pulse minimum duration (e.g., 50us)
u32	t0h_max_ns	Bit 0 high time maximum (e.g., 550ns)
u32	t0h_min_ns	Bit 0 high time minimum (e.g., 250ns)
u32	t0l_max_ns	Bit 0 low time maximum (e.g., 1000ns)
u32	t0l_min_ns	Bit 0 low time minimum (e.g., 700ns)
u32	t1h_max_ns	Bit 1 high time maximum (e.g., 950ns)
u32	t1h_min_ns	Bit 1 high time minimum (e.g., 650ns)
u32	t1l_max_ns	Bit 1 low time maximum (e.g., 600ns)
u32	t1l_min_ns	Bit 1 low time minimum (e.g., 300ns)
