Analog-to-Digital Converter (ATD10B16CV1)
7.1 Introduction
The ATD is an 16-channel, 10-bit, multiplexed input successive approximation analog-to-digital converter.
Refer to device electrical specifications for ATD accuracy.
The block is designed to be upwards compatible with the 68HC11 standard 10/8-bit A/D converter. In
addition, there are new operating modes that are unique to the HC12 design.
7.1.1 Features
• 8/10-bit resolution.
• 7 µs, 10-bit single conversion time.
• Sample buffer amplifier.
• Programmable sample time.
• Left/right justified, signed/unsigned result data.
• External trigger control.
• Conversion completion interrupt generation.
• Analog input multiplexer for 16 analog input channels.
• Analog/digital input pin multiplexing.
• 1-to-16 conversion sequence lengths.
• Continuous conversion mode.
• Multiple channel scans.
• Configurable external trigger functionality on any ATD channel.
• Configurable location for channel wrap around (when converting multiple channels in a sequence).
