Analog to Digital Converter (ADC) Interface
DM36x has a 6-channel, 10-bit analog-to-digital converter (ADC) interface. The CPU communicates to the
ADC interface using 32-bit-wide control registers accessible via the internal peripheral bus.
ADC interface using 32-bit-wide control registers accessible via the internal peripheral bus.
The DM36x ADC interface has following features:
•
Supports six configurable analog Input
•
Supports for successive approximation type 10-bit, A-D converter
•
Programmable sampling / conversion time (base clock is AUXCLK)
•
Supports channel select by auto scan conversion
•
Supports mode select by one-shot mode or free-run mode
•
Programmable setup (Idle) period to secure A/D sampling start time
•
Supports the clock stop signals to connect the PSC
