Analog-to-Digital Converter (ADC)
5.1 Overview
5.1.1 Device-specific features
• 10-bit resolution
• As many as 16 channels, expandable to 23 channels via external multiplexing
• Minimum conversion time of 1 µs
• Conversion triggering sources:
— Software
— PIT channel 2 (for normal conversion trigger only)
• Two different sampling and conversion time registers CTR[1:2] (extended internal channels,
external channels)
• As many as 23 data registers for storing converted data; conversion information, such as mode of
operation (normal, injected), is associated to data value
• Conversions on external channels managed in the same way as internal channels, making it
transparent to the application
• External decode signals (3 bits) to control the external analog multiplexers
• One Shot/Scan modes
• Chain Injection mode
• Hardware-triggered DMA transfer requests
• Power-down mode
• Two different Abort functions provide the ability to abort either single-channel conversion or chain
conversion
• Four programmable analog watchdogs with interrupt capability
— Allows continuous hardware monitoring of as many as four analog input channels
— Alternate analog thresholds
• Auto-clock-off
