4.5.5.1 16-bit Analog-to-Digital Converter (ADC)
• Linear successive approximation algorithm with up to 16-bit resolution
•
Output modes:
• Differential 16-bit, 13-bit, 11-bit, and 9-bit modes, in two’s complement 16-bit sign-extended format
• Single-ended 16-bit, 12-bit, 10-bit, and 8-bit modes, in right-justified unsigned format
• Single or continuous conversion
• Configurable sample time and conversion speed/power
• Conversion complete and hardware average complete flag and interrupt
• Input clock selectable from up to four sources
• Operation in low power modes for lower noise operation
• Asynchronous clock source for lower noise operation with option to output the clock
• Selectable asynchronous hardware conversion trigger with hardware channel select
• Automatic compare with interrupt for various programmable values
• Temperature sensor
• Hardware average function
• Selectable voltage reference
• Self-calibration mode
4.5.5.2 High-Speed Analog Comparator (CMP)
• 6-bit DAC programmable reference generator output
• Up to eight selectable comparator inputs; each input can be compared with any input by any polarity sequence
• Selectable interrupt on rising edge, falling edge, or either rising or falling edges of comparator output
• Comparator output supports:
• Sampled
• Windowed (ideal for certain PWM zero-crossing-detection applications
• Digitally filtered using external sample signal or scaled peripheral clock
• Two performance modes:
