3.3.1 Digital Input Signal Connection (TTL DI/O, Pull-Up)
A digital input/output (DI/O) channel can be configured by software to perform digital
input measurement, which is the power-on default configuration, or digital output
generation. When performing digital input measurement, the voltage logic level
between the digital input (DI) terminal and the digital ground (DGND) terminal is mea-
sured. To prevent undetermined or fluctuating results when input is floating, the digi-
tal input channel is internally pulled-up. This is shown in Figure 3.3.
