continuous blocks, then the integration step size determines the base sample
rate.
For example, if the model code is a controller operating at 100 Hz, then every
0.01 seconds the background task is interrupted. During this interrupt, the
controller reads its inputs from the analog-to-digital converter (ADC),
calculates its outputs, writes these outputs to the digital-to-analog converter
(DAC), and updates its states. Program control then returns to the background
task. All of these steps must occur before the next interrupt.
