Analog-to-Digital Converter (ADC0)
Section 3.13 shows the global view of the ADC module with its functional blocks and
interfaces and the features which are provided by the module.
Figure 3-10
Block Diagram of the ADC Module
The ADC module has 16 analog input channels. An analog multiplexer selects the input
line for the analog input channels from among 32 analog inputs. Additionally, an external
analog multiplexer can be used for analog input extension. External Clock control,
address decoding, and service request (interrupt) control are managed outside the ADC
module kernel. External trigger conditions are controlled by an External Request Unit.
This unit generates the control signals for auto-scan control (ASGT), software trigger
control (SW0TR, SW0GT), the event trigger control (ETR, EGT), queue control (QTR,
QGT), and timer trigger control (TTR, TGT).
An automatic self-calibration adjusts the ADC module to changing temperatures or
process variations. Figure 3-10 shows the global view of the ADC module with its
functional blocks and interfaces.
