Analog-to-Digital Converter (ADC)
29.1 Introduction
The 12-bit analog-to-digital converter (ADC) is a successive approximation ADC
designed for operation within an integrated microcontroller system-on-chip.
29.1.1 Features
Features of the ADC module include:
Freescale Semiconductor, Inc.
• Linear successive approximation algorithm with up to 12-bit resolution
• Up to 24 single-ended external analog inputs
• Output modes: single-ended 12-bit, 10-bit and 8-bit modes
• Output in right-justified unsigned format for single-ended
• Single or continuous conversion (automatic return to idle after single conversion)
• Configurable sample time and conversion speed/power
• Conversion complete / 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 hardware conversion trigger with hardware channel select
For the chip specific modes of operation, refer to the Power
Management information for the device.
