Your sentence is true. NRD and NCS cycle time must be the same (otherwise SMC behaviour is undefined), hence both signals start/finish simultaneously. Anyway waveforms (setup, and pulse time) can be different. All of thise are kinda obvious, no? :-) Stanislaw -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
