1) The specified delay times refer to the hardware. The actual reaction time depends on the time slot in which the digital input or output is processed.
2) If the analog input is to be operated in the signal processing sense with continuously variable input voltage, the sampling frequency fa = 1/ttime slice must be at least twice the value of the highest signal frequency fmax.
